Perhaps you need the reaction between $CaCO_3$ and HCl:

$CaCO_3 + 2HCl\ \to\ CaCl_2 + CO_2 + H_2$

How many moles are in 50 g of CO2

murzikaleks [220]

Answer:

1.1 mol

Explanation:

n=m/M, where n is moles, m is mass, and M is molar mass.

M of CO2 = 12.01+16.00+16.00 = 44.01g/mol

n=50g/44.01g/mol

n = 1.13610543 mol

n ≈ 1.1 mol

a vehicle accelerates with 0.4 m/s. calculate tue time taken by the vehicle to increase its speed from 20m/s to 40m/s.

Grace [21]

Answer:

$\huge\boxed{\sf t = 50 \ seconds}$

Explanation:

<h3><u>Given data:</u></h3>

Acceleration = a = 0.4 m/s²

Initial Speed = $V_i$ = 20 m/s

Final Speed = $V_f$ = 40 m/s

<h3><u>Required:</u></h3>

Time = t = ?

<h3><u>Formula:</u></h3>

$\displaystyle a =\frac{V_f-V_i}{t}$

<h3><u>Solution:</u></h3>

Rearranging formula for t

$\displaystyle t =\frac{V_f-V_i}{a} \\\\t = \frac{40-20}{0.4} \\\\t = \frac{20}{0.4} \\\\\boxed{t = 50 \ seconds}\\\\\rule[225]{225}{2}$
