Answer: bale 2 elements sya ang mga yon ay hydrogen at oxygen.

H2O is a molecule made of H for hydrogen and O for oxygen. There are 12 of these molecules. The smaller number is the number of atoms of the element to the left of it.

MARK ME AS A BRAINLIEST PLEASE

H₂O, which represents a molecule of water, consists of three atoms: two hydrogen atoms (H) and one oxygen atom (O). Therefore, H₂O contains a total of three elements: hydrogen and oxygen.

H₂O represents a molecule of water. The "H" stands for hydrogen, and the "O" stands for oxygen.

Hydrogen (H) is a chemical element with the atomic number 1. It is the lightest and most abundant element in the universe. Hydrogen atoms consist of a single proton in the nucleus and one electron in orbit around the nucleus.

Oxygen (O) is a chemical element with the atomic number 8. It is a highly reactive and abundant element, making up a significant portion of the Earth's atmosphere and the compounds found on Earth. Oxygen atoms consist of eight protons in the nucleus and eight electrons in orbit around the nucleus.

Answer:The relationship which is between bacteria and ungulates with the intestine is or good example of mutualism. Mutualism plays an important role in ecology. We can say that if we measure the exact fitness what we get as a benefit is a mutualistic relationship.example of a mutualistic relationship is that of the oxpecker (a kind of bird) and the rhinoceros or zebra. Oxpeckers land on rhinos or zebras and eat ticks and other parasites that live on their skin. The oxpeckers get food and the beasts get pest control.

Answer:

Well i know that a chemical change is somthing that can not be undone.

This however is a physical change let me explain.

Even though you mixed two chemicals together to create a new substance does NOT mean it is a chemical change. This however is kinda like a water. You can turn water into a ice cube that does not mean it changed what the water is made out of it just changed the form of the water. Kinda like this. A chemical change would be an example of buring a log once that log has turned into ashs it will never be the log it was before.

Answer: The magnesium 24, 25, and 26 atoms are isotopes because they all have the same number of protons but they have different mass numbers

Explanation: isotopes of an element have the same number of protons but different mass number. So for magnesium 24, the number of protons is 12 and the number of neutrons is 12.

For magnesium 25, the number of protons would still be 12 but the neutrons would be 13.

Magnesium 26, the number of protons would be 12 and neutrons number is 14

i only found the 49, hope it still helps, mate

49. In this question (t½) of C-14 is 5730 years, which means that after 5730 years half of the sample would have decayed and half would be left as it is.

After 5730 years ( first half life) 70 /2 = 35 mg decays and 35 g remains left.

After another 5730 years ( two half lives or 11460 years) 35 /2 = 17.5mg decays and 17.5 g remains left .

After another 5730 years ( three half lives or 17190 years) 17.5 /2 = 8.75mg decays and 8.75g remains left.

after three half lives or 17190 years, 8.75 g of C-14 will be left.

Answer:

Magnesium is the limiting reactant.

Explanation:

The balanced reaction is:

2 Mg + O₂ ⇒ 2 MgO

By stoichiometry of the reaction (that is, the relationship between the amount of reagents and products in a chemical reaction), the following quantities participate in the reaction:

Being the molar mass:

Then the following quantities of mass participate in the reaction:

The limiting reagent is one that is consumed first in its entirety, determining the amount of product in the reaction. When the limiting reagent is finished, the chemical reaction will stop.

To determine the limiting reagent, it is possible to use the reaction stoichiometry of the reaction. You can use a simple rule of three as follows: If by stoichiometry of the reaction 32 grams of oxygen react with 48.62 grams of magnesium, 12.5 g of oxygen will act with how much mass of magnesium?

[tex]mass of magnesium=\frac{12.5 g of oxygen*48.62 grams of magnesium}{32 grams of oxygen}[/tex]

mass of magnesium= 18.99 grams

But 18.99 grams of magnesium are not available, 3.80 molesgrams are available. Since you have less mass than you need to react with 12.5 grams of oxygen, magnesium will be the limiting reagent.

Answer:

2.088464 grams.

Explanation:

The density of neon is 0.9002 g/L. Multiplying this value by the number of liters gives how many grams of neon it contains.

0.9002(2.32) = 2.088464

Answer:

The difference in velocity divided by rate = acceleration.

80 - 10 = 70km/h

60 sec. per hour, so 70 × 60 = 4,200 km/s

4.200/8=525

520/60 = 8.6666666667 km/h

Explanation:

Not the answer but hope it puts you in the neighborhood.

The resultant acceleration of the car is 2.43 m/s².

Acceleration is define as the rate of change of velocity with respect to the time and it will be calculated as:

Acceleration = Velocity / Time

Given that, velocity of car = 80km/h - 10km/h = 70km/h

As we know that 1 km = 1000m

and 1 hour = 3600 sec

So that 70km/h = 19.4 m/s

Given time = 8 sec

Now putting values on the acceleration equation, we get

Acceleration = 19.4 m/sec / 8sec = 2.43 m/s²

Hence required acceleration is 2.43 m/s².

Explanation:

The empirical formula of a compound is defined as the simplest whole number ratio of the atoms present in a molecule. As we have in the molecule Carbon, Hydrogen and Oxygen to find the simplest ratio we need to divide each number of moles in the moles of Oxygen (The lower number). As follows:

C = 0.5mol C / 0.25mol O = 2

H = 1 mol H / 0.25mol O = 4

O = 0.25mol O / 0.25mol O = 1

The empirical formula is:
