1. Both light bulbs will stop glowing
2. The other light bulb will stay on but get dimmer
3. the other light bulb will stay on and glow more brightly
4. the battery will lose its charge and stop working

Answer:

1. Are Metals

2. Are Solids

3. Are Un-reactive

4. Have 18 valence electrons

Explanation:

In a color coded periodic table of the components, the crate for every component is colored. This tone speaks to the classes of components, which incorporate metals, metalloids and non-metals. All in all, the color blue is used for metals, orange for metalloids and green for non-metals. The periodic table might be further tone coded to incorporate different gatherings, for example, transition metals, rare earths, alkali metals, alkaline earths, halogens and noble gases.

The modern periodic table coordinates components by their nuclear number, which is extraordinary to every component. The nuclear number speaks to the quantity of protons in a particle of the component. In the cutting edge occasional table, the nuclear number increments from left to right and through and through. The occasional table is likewise coordinated into periods and groups. Periods are the rows and groups are the columns. The components in every period start with metals on the left side, at that point move to metalloids and afterward to non-metals on the right. The components contained in each group have comparative actual properties.

Explanation:

Methane is a gas at room temperature but methanol is a liquid because in methane there's London dispersion intermolecular force but in methanol there's H-bond and London dispersion force. H-bond is more stronger than London dispersion force. So, it increases the boiling point of methanol that's why methane is gas at room temperature due to weak attraction of London dispersion force and methanol is liquid.

Methanol has a higher boiling point than methane due to stronger intermolecular forces (IMFs), or attraction between individual molecules. This makes its molecules more difficult to separate, requiring more energy and resulting in a higher boiling point.

An intermolecular force is a force that mediates the interaction of molecules, including electromagnetic forces of attraction or repulsion that act between atoms and other types of neighboring particles, such as atoms or ions.

Intermolecular forces are classified into five types namely,

Between ions and polar dipole molecules, ion-dipole forces exist.

Since of stronger intermolecular forces (IMFs), or attraction between individual molecules, methanol has a higher boiling point than methane.

This makes it more difficult to separate its molecules, requiring more energy and resulting in a higher boiling point.

Thus, this is the reason of using types of intermolecular forces present.

The number of Na atoms in the reactants = 2

Every chemical reaction involves compounds that can act as reactants or products

The reactants will react to produce products

The reactants are usually written on the left side of the reaction, while the products on the right side of the reaction

Reaction

2 NaCl + H₂SO₄ → 2 HCl + Na₂SO₄

The element with atomic number 11  = Na(Natrium)

The number of atoms of the element that reacts or is produced can be seen from the reaction coefficient and the number of atoms in the compound

Na in NaCl = 1 atom

From equation, cofficient for NaCl = 2, so number of atoms of Na=2 x 1 = 2

Answer: Molar mass is the amount grams that one mole weighs.

Explanation: You need to find the molar mass of NaCl which is the same as the amu on the periodic table in grams. So it is 22.99(Na) + 35.45(Cl) = 58.44

You also know that for every mole of NaCl you have 1 mole of Na because every molecule of NaCl has 1 atom of Na.

Finally, using the periodic table, again, you see that the molar mass of Na is 22.99.

Then using stoichiometry, you can find the grams of sodium.

100(g NaCl) * 1 mol (NaCl)/58.44 g (NaCl) * 1 mol (Na)/ 1 mol (NaCl) * 22.99 (g of Na)/ 1 mol (Na)

which equals 39.339435 g of Na.

If you need to maintain significant figures the answer will be 40.

Answer:

1.58 102 mol

Explanation:

I just looked it up on Quizlet.

1.58 102 moles of NaOH must be dissolved in 1.00 L of water to make NaOH (aq) with a pH of 12.2.

One mole of any substance weighs about the same as the molecular mass of that substance. Hence, the number of moles of sodium hydroxide contained in 160 g of it is 4 moles.

Number Of Moles Formula

670.956

Explanation:

You can use this equation to solve for heat :

Q = m * c * ΔT

Q represents the heat

m represents the mass in kilograms

c is the specific heat. For aluminum, it's 897

ΔT is the change in temperature, so, 49 - 15 which is 34

Plug in the numbers and you get this :

Q = 0.022 * 897 * 34

Q = 670.956 Joules

Explanation:

Answer: D

Explanation: P = W/t

W = F d

When dividing, if you have a large number over a small, you get a large number. We want a small number, so we want the opposite for our P : W/ t formula. We want a small Work and a large time.

Right off the bat, the two with the least time aren't right then.

From there, we can estimate how much work it would take using the W = F d equation. If there is a small distance, there is less work, which is what we want to achieve a small work over large time.

So, the choice with the most time and the least distance should be correct.

Answer:

Mass = 50kg, a = 20m/sec^2

F = MA

F = 50 * 20

F = 1000N

F = MA

650 = M * 10

M = 650/10 = 65kg

The phenomenon of weightlessness occurs when there is no force of support on your body. when your body is effectively in free fall, accelerating downward at the acceleration of gravity, then you are not being supported.

F = Gm1m2/distance^2

F = 6.6726* 10 ^-11 * 70 * 5.98 * 10^24/(6.38 * 10^6)^2

Propane and butane are pure substances, which means that each one of them is made of only one type of molecule—propane molecules or butane molecules. In contrast, gasoline, diesel, and kerosene are not pure substances; they are mixtures of more than one substance.

Explanation:

Hope it is helpful...

Propane, butane, gasoline, diesel and kerosene are all hydrocarbons. They  can be produced from petroleum. All these are used as fuels.

Hydrocarbons are organic compounds containing  C-C backbone and C-H bonds, These compounds are composed of carbons and hydrogens. Different function groups can be added to the hydrocarbons to form  various organic compounds such as acids, esters , aldehydes, ketones etc.

Methane is the first hydrocarbon in the hierarchy based on number of carbons. Propane is third in this series since it contains 3 carbons and butane is 4th one. Gasoline, diesel and kerosene are all hydrocarbons with different carbon numbers.

All these are obtained  as a byproduct of petroleum. These are used as fuel in vehicles and house holds.  The difference in them is the number of carbon and hydrogen.
