Answer : There are 7.0 moles of oxygen in the formula.
Explanation :
The chemical formula of nickel tetracarbonyl is Ni(CO)₄.
We can see that there are 4 carbon atoms and 4 oxygen atoms which together form 4 carbonyl (CO) groups.
Therefore the mole ratio of C to O is 1 : 1.
Let us use this as a conversion factor to find moles of oxygen.
We have 7.0 moles of carbon in the formula.
The moles of O can be calculated as,
There are 7.0 moles of oxygen in the formula.
Arietis, camelopardalis, lyncis, scorpii, cancri, canis minoris
Answer:
The correct option is (a).
Explanation:
We need to find the product of given numbers.
First number = 29.5
Second number = 240
Product of two numbers = 29.5 × 240
= 
Zeroes from numerator and denominator get cancelled.
So,
Hence, the correct option is (a).
The reaction, 2 C4H10 (g) + 13 O2 (g) = 8 CO2 (g) + 5 H2O (g), is the combustion of butane. A combustion reaction involves the reaction of a hydrocarbon with oxygen producing carbon dioxide and water. This reaction is exothermic which means it releases energy in the form of heat. Therefore, as the reaction proceeds,a heat energy is being given off by the reaction. This happens because the total kinetic energy of the reactants is greater than the total kinetic energy of the products. So, the excess energy should be given off somewhere which in this case is released as heat.
Voltage difference is the push that causes charges to flow from high to low areas.
