Is Ca + O --> CaO a balanced chemical equation? Is it obeying the law of conservation of matter? Question 5 options: Yes it i

s balanced. It has the same number of Ca and O on both the reactant side and the product side. No it is not balanced. It has more Ca on the product side than the reactant side. No it is not balanced it has more O on the reactant side than the product side.

Answer is: Yes it is balanced. It has the same number of Ca and O on both the reactant side and the product side.

According to principle of mass conservation, number of atoms must be equal on both side of chemical reaction.

There is one calcium atom atom and one oxygen atom on both side of reaction, so chemical reaction is balanced.

ASAP<br>what is an electron cloud ​
Bad White [126]

Explanation:

An electron cloud is the region of space that surrounds the nucleus of an atom under the nucleus of the negatively charged sub-atomic particles.

  • An atoms is made up of some particles.
  • The proton is positively charged and it is located in the nucleus of an atom.
  • The neutrons do not carry any charges and occupies the nucleus with protons.
  • Electrons are the negatively charged particles outside the nucleus.
  • The electron cloud is portion of an atom with greatest probability of finding an electron.

What is the mass of an object that has a density of 0.500 g/cm3 and a volume of 5.00 mL?
attashe74 [19]

Answer:

<h2>The answer is 2.5 g</h2>

Explanation:

The mass of a substance when given the density and volume can be found by using the formula

<h3>mass = Density × volume</h3>

From the question

density = 0.5 g/cm³

1 mL = 1 cm³

5 mL = 5 cm³

volume = 5 cm³

The mass is

mass = 0.5 × 5

We have the final answer as

<h3>2.5 g</h3>

Hope this helps you
