Molar mass of :
O2 = 16 * 2 = 32 g/mol
CO2 = 12 + 16 * 2 = 44 g/mol
<span>Balanced chemical equation :
</span>
1 CH4 +
2 O2 =
1 CO2 +
2 H2O
↓ ↓
2 moles 1 mole
2* 32 g O2 ----------> 1* 44 g CO2
x g O2 ------------> 10.0 g CO2
44 x = 2 * 32*10.0
44 x = 640
of O2
A: the ball in frame A had the highest velocity, and the ball in frame B has the highest kinetic energy
Answer is: this is synthesis reaction.<span>
</span>Chemical reaction: Ba + F₂ → BaF₂.
Synthesis reaction<span> is a type of reaction in which multiple reactants combine to form a single product.
</span>In barium fluoride, barium has oxidation number +2 and fluorine has oxidation number -1, so compound has neutral charge.
The answer is 4 (four).
Hope this helps!!! :)
Answer:
Explanation:
Hello,
The frequency and wavelength of electromagnetic waves propagating in free space might be related to each other by using the following equation:
c=λf
Solving for the frequency:
f=c/λ
Knowing that λ stands for the wavelength (642 nm for the mentioned incident light), c the light velocity (300.000 m/s) and f the frequency, we get the asked frequency as:
}
Best regards.
