Answer:
Explanation:
Number of moles of propane:
=Mass in grams ÷ Relative molecular Mass
= 100/((12*3) + (1*8))
= 100 ÷ 44
= 2.2727
Mole ratio propane:carbon (IV) oxide = 1:3(from the equation)
Number of moles of CO2 = 3*2.2727 = 6.8181
Mass in grams = Relative molecular Mass * Number of moles
= 44 * 6.8181
= 299.9964 grams
Answer:
To convert C to K, just add 273, remember that 0° C is 273 K, so 73.a) is 317.2 K and 73.c) is 253 K. 74.a) Will be, -129, 4 C + 273 = 143.5 F, 74.c) 663.8 F
75.a) 7.2 C , 75.c) -23.3 C
Explanation:
To convert C to F, you can use this, (9/5 * C + 32 ) = F, or back ward, C = (F - 32)* 5/9.

The atomic number of the product decrease by one in the d) positron emission and the e) electron capture radioactive decay. These radioactive decays are two of three common forms of the Beta Decay which occurred when the proton released a positron and a neutron emitted an electron<span>. The Beta Decay can increase or decrease the atomic number.</span>
