Answer:
it will take that explosin 15.34 millisecond
Explanation:
as the speed is 767 and distance is 50 so time will be 767/50=15.34milliseconds
To determine the amount of oxygen that is present in the compound, we have to assume that the given compound contains carbon, hydrogen and oxygen only or else we will not be able to determine the answer. We need to convert the moles of the elements given to units of grams by using the atomic mass of these elements. Then, from the total amount of the compound we subtract the masses of the elements. We do as follows:
mass
0.117 mol C ( 12.01 g / 1 mol ) = 1.41 g
0.233 mol H ( 1.01 g / 1 mol ) = 0.24 g
Mass O = 3.50 g - 1.41 g - 0.24 g = 1.85 g O
Moles O = 1.85 g O ( 1 mol / 16 g ) = 0.116 moles O
The question gives us a conversion factor---> 1 mm3= 7.0 x 10^6 RBC. so, to find how many red blood cells we have, we first need to convert the Liters to cm3 using this conversion factor--> 1 mL= 1 cm3
i have attached how to solve this problem.
Answer:
.
Explanation:
i'm not sure what the question is, but the reason the cake in the pan is hotter is because the pan was still hot from the oven, while the air is cooler, surrounding the cake on the plate and cooling it faster.
