borishaifa [10]3 years ago
8 0
328 % means 0.328 g of KCN in 100 g of solution

0.328 g of KCN ---------> 100 g of solution

1120 * 10^-3 g of KCN ------> (100 / 0.328) * 1120 * 10^-3

= 341 g of solution

using the symbol M for the element, write the chemical formula for the compound that forms when element M reacts with iodine.
Anon25 [30]

Answer : The chemical formula for the compound is, MI

Explanation :

When the element 'M' react with the I_2 to give MI.

The balanced chemical reaction is,

2M+I_2\rightarrow 2MI

In this reaction, 'M' is in mono-atomic form and I_2 is in diatomic form.

By the stoichiometry,

2 moles 'M' react with the 1 mole of I_2 to give 2 moles of MI.

Therefore, the chemical formula of the compound is, MI

What is the engine piston displacement in liters of an engine who’s displacement is listed as 430 in.²
sergeinik [125]

For an engine whose displacement is listed as 430 in.², the engine piston displacement in liters is mathematically given as

PD= 7.37 L  

<h3>What is the engine piston displacement in liters of an engine whose displacement is listed as 430 in.²?</h3>

Generally, the equation for the dimensional analysis method,\, we convert in to L is mathematically given as

l*(v/l)*l/v

Therefore,  piston displacement

PD=(450 in3) . (1 dm3 / 61.024 in3) . (1 L / 1 dm3)

PD= 7.37 L  

In conclusion, piston displacement

PD= 7.37 L
