Which option describes cations?

A: elements that readily give off electrons in a chemical reaction
B: a family of elements located in Group 17 of the periodic table
C: positively charged ions
D: elements that tend to accept electrons when they engage in chemical reactions

Answer:

D.) solidify

Explanation:

Answer:

The speed of wavelength is 3.0 ×10³ m/s.

Explanation:

Given data:

De Broglie wavelength = 132 pm (132×10⁻¹² m)

Speed of wavelength = ?

Solution:

Formula:

λ = h/mv

λ = wavelength

h = planck's constant

m = mass of proton

v = speed

now we will put the values in formula.

132×10⁻¹² m = 6.63 ×10⁻³⁴ j.s / 1.67 ×10⁻²⁷ kg × v

v =  6.63 ×10⁻³⁴ j.s / 1.67 ×10⁻²⁷ kg × 132×10⁻¹² m

j = kg m²/s²

v = 6.63 ×10⁻³⁴ kg m²/s / 1.67 ×10⁻²⁷ kg × 132×10⁻¹² m

v = 6.63 ×10⁻³⁴ kg m²/s / 220.44 ×10⁻³⁹ kg.m

v = 0.03×10⁵ m/s

v = 3.0 ×10³ m/s

The speed of wavelength is 3.0 ×10³ m/s.

Using the Law of Conservation of mass,the mass of the reactants should be equal to the mass of the products after the reaction.

Answer:

The answer is A.

Explanation:

Neutrons and protons are located in the dense middle of the atom called the nucleus, and electrons are located on the electron cloud located outside of the nucleus.

The value of the equilibrium constant shows the relative amounts or concentrations of the reactants and products.

Answer:

"Critical thinking is the analysis of available facts, evidence, observations, and arguments to form a judgment. The subject is complex; several different definitions exist, which generally include the rational, skeptical, and unbiased analysis or evaluation of factual evidence. Critical thinking is self-directed, self-disciplined, self-monitored, and self-corrective thinking. It presupposes assent to rigorous standards of excellence and mindful command of their use. It entails effective communication and problem-solving abilities as well as a commitment to overcome native egocentrism and sociocentrism." - Searched it up on Wiki, so at least I stated this-.

Answer:

0.531 moles of CO₂ are formed.

Explanation:

Given data:

Number of moles of CO = 0.531 mol

Number of moles of CO₂ formed = ?

Amount of oxygen = excess

Solution:

Chemical equation:

2CO + O₂    →    2CO₂

Now we will compare the moles of CO with CO₂.

              CO            :            CO₂

                2             :              2

              0.531        :          0.531

Thus, 0.531 moles of CO₂ are formed.

Explanation: When the little finger bends in towards the palm and can't be straightened out, it is known as streblomicrodactyly, streblodactyly or camptodactyly.

Little fingers range from perfectly straight to bending inwards at a sharp angle. It is not clear whether fingers fall into two discrete categories or there is a continuous range of pinky angle. Hersh et al. (1953) said that bent little fingers bend inward at an angle of 15 to 30 degrees. They found that only 4 out of a sample of 4,304 people had what they considered to be bent little fingers

If only extremely bent little fingers are considered, then the bent little finger trait is too rare to be useful for illustrating basic genetics in classrooms. If fingers with a more moderate bend are counted, then there is no clear dividing line between bent and straight, plus no evidence that the trait is genetic. In either case, you should not use bent little finger to demonstrate basic genetics.

 Bent Little Finger :  A dominant allele results in the end joint of the little finger of each hand bending inward.  Straight little fingers are a result of the recessive genotype.

Place your hands on a flat surface, palms down, and relax.  Check to see if the first joints of your little fingers are bent or straight.

There you go

Explanation:

The higher the elevation the cooler the air therefore the climate becomes colder.

Answer: C

Explanation:

The force of gravity is proportional to the amount of mass in the system, and is inversely proportional to the separation distance between the two masses.

Adding mass to one of the objects would increase the gravitational field it produces, which in return increases the force of gravity.

Increasing the charge of one of the objects would technically add mass to the system, but it can be considered negligible. The adding of charge would cause an attraction between the two objects, but that is not the gravitational force. It is the Coulomb force.

Reducing the mass of one of the objects would decrease the gravitational field it produces, which would cause the force of gravity to decrease. This is the answer.

Moving the objects closer would cause the denominator of the force equation to decrease. A smaller denominator would cause the equality to increase, aka the gravitational force.

Answer: I think it’s either C or Dz

Explanation:

Due how it’s calculated.

The calculation that will not give the correct average atomic mass is  (60⋅12)+(40⋅13).

The average atomic mass is obtained as the sum of the products of the relative abundance of each isotope multiplied by its mass.

There are 6 C-12 isotopes and 4 C-13 isotopes. This gives a total of 10 isotopes of both types.

All calculations of average atomic mass are correct except (60⋅12)+(40⋅13).
