Answer:
Ths answer is B as increasing 10k per week
I’m pretty sure it’s D because energy measures the kinetic, thermal, electrical, chemical, nuclear and other forms.
Answer:
Two significant figures
Step-by-step explanation:
In <em>multiplication </em>problems, your answer can have no more significant figures than the number with the <em>fewest significant figures</em>.
2.05 cm × 32 cm = 65.600 000 00 cm² (by my calculator)
There are three significant figures in 2.05, but only two in 32.
You must round to <em>two</em> significant figures and report the answer as 66 cm².
65.600 000 00 cm² ⟶ 66 cm²
Answer:
9.4L
Explanation:
Given parameters:
Mass of Cl₂ gas = 30g
Unknown:
Volume of gas = ?
Solution:
To solve this problem, let us assume that this reaction takes place under standard temperature and pressure conditions.
Therefore;
Volume of gas = number of moles x 22.4
To find the number of moles;
Number of moles =
molar mass of Cl₂ = 2(35.5) = 71g/mol
Number of moles = = 0.42mole
So;
Volume of gas = 0.42 x 22.4 = 9.4L
