<u>Answer:</u>
<em>The chocolate bar has 30 grams of fat, if it has 270 fat calories. </em>
<u>Explanation:</u>
Nourishment calories are characterized as the measure of warmth vitality required to raise the temperature of one kilogram of water by one degree Celsius.
The micro nutrients in our nourishment like proteins, fats and starches has their particular commitment to the absolute nourishment calorie which was taken by the human.
It is realized that every gram of fat adds to 9 calories in any nourishment thing.
1 g of Fat= 9 fat calories
1 fat calories= 19 g of fat
270 fat calories= of fat = 30 g of fat
Thus 270 fat calories will contain 30 g of fat in it.
<u>Answer:</u> The chemical equation is written below.
<u>Explanation:</u>
Transmutation is defined as the process in which one chemical isotope gets converted to another chemical isotope. The number of protons or neutrons in the isotope gets changed.
The chemical equation for the reaction of curium-242 nucleus with alpha particle (helium nucleus) follows:
The product formed in the nuclear reaction are californium-245 nucleus and a neutron particle.
The mass of CO₂ gas produced during the combustion of one gallon of octane is 8.21 kg.
The given parameters:
<em />
The mass of the octane burnt is calculated as follows;
The combustion reaction of octane is given as;
From the reaction above:
228.46 g of octane -------------------> 704 g of CO₂ gas
2,664.37 of octane --------------------> ? of CO₂ gas
Thus, the mass of CO₂ gas produced during the combustion of one gallon of octane is 8.21 kg.
