Hello!

The coefficients of any chemical compound are located in the front.

We are asked to find the coefficient of CaCl2 when the equation is balanced. Before finding the coefficient, we should determine if the equation is balanced or not.

Right side: 1 Ca, 2 H, 2 Cl

Left side: 1 Ca, 2 H, 2 Cl → This equation is balanced!

Since the compound CaCl2 has no number in from of the compound, the coefficient has to 1.

Therefore, the coefficient for CaCl2 is 1.

Will give brainliest! if 32.0 g of hcl is to be diluted to make a 4.80 m solution, how much water should be added?
nadezda [96]

The required volume of water is 0.18 liters.

<h3>What is molarity?</h3>

Molarity of any solution is define as the number of moles of solute present in per liter of solution as;

M = n/V

Moles of solute will be calculated as:

n = W/M, where

W = given mass of HCl = 32g

M = molar mass of HCl = 36.4g/mol

n = 32 / 36.4 = 0.88 mole

Given molarity of solution = 4.80M

On putting all values in the above equation, we get

V = (0.88) / (36.4) = 0.18 L

Hence required volume of water is 0.18L.

How many atoms are in the 3.5 moles of arsenic atoms?
Dmitry_Shevchenko [17]
Number of atom in one mole = 6.022 × 10²³
So, in 3.5 moles, it would be: = 6.022 × 10²³ * 3.5 = 2.1 × 10²⁴

In short, Your Answer would be 2.1 × 10²⁴ atoms

Hope this helps!
