Answer:
1000 g
Explanation:
d = m/v
We are given d: 10g/cm3
and v: 100cm3
Plug them into the equation to get 10 = m/100
Then, cross multiply 10x100 to get mass which is: 1000g
Answer:
What is the net ionic equation for a reaction between HCl and NaOH?
Explanation:
A salt is a neutral ionic compound. Let's see how a neutralization reaction produces both water and a salt, using as an example the reaction between solutions of hydrochloric acid and sodium hydroxide. The overall equation for this reaction is: NaOH + HCl → H2O and NaCl
Hope that helped.
Answer:
The new volume of the gas is 4.74L
Explanation:
Data;
T1 = 14°C = (14 + 273.15)K = 287.15K
V1 = 4.5L
T2 = 29°C = (29 + 273.15)K = 302.15
V2 = ?
From Charles law,
The volume of a fixed mass of gas is directly proportional to its temperature provided that pressure remains constant.
Mathematically,
V = kT
k = V1 / T1 = V2 / T2 = V3 / T3 = .............= Vn / Tn.
V1 / T1 = V2 / T2
Solving for V2
V2 = (V1 * T2) / T1
V2 = (4.5 * 302.15) / 287.15
V2 = 4.735L
V2 = 4.74L
The new volume of the gas is 4.74L
