Ethyl Alcohol Rubbing Alcohol. The other type of rubbing alcohol consists of 97.5-100% denatured ethyl alcohol or ethanol with water. Ethyl alcoholnaturally is less toxic than isopropyl alcohol. ... In fact, in the US, additives make it as toxic asisopropyl alcohol.
Answer: 0.0195g of CO2 is produced
Explanation:
CH4 + 2O2 —> CO2 + 2H2O
Molar Mass of CO2 = 12 + (16x2) = 12 + 32 = 44g/mol
Molar Mass of CH4 = 12 + (4x1) = 12 + 4 = 16g/mol
From the equation,
16g of CH4 produce 44g of CO2.
Therefore 7.10×10^−3 of CH4 will produce Xg of CO2 i.e
Xg of CO2 = (7.10×10^−3x44) /16 = 0.0195g
Photon
energy is the energy carried by a single photon with a certain wavelength and
frequency. These terms are related by an equation. <span>
E = hv
where h is the Planck's constant (6.626 x
10-34 J s), v is the frequency.</span>
We calculate the energy as follows:
E = hv
E = 6.626 x 10-34 J s ( 7.31 × 10^14 / s ) = 4.84 x 10^-19 J

MgCl2 = 1Mg + 2Cl = 1(24.3) + 2(35.45) = 95.2g/1mole
7.50moles MgCl2 x 95.2g MgCl2 = 714g MgCl2
