Significant Figures For 7.06 × 10^5 ÷ 5.3 × 10^-2
Kay [80]

Answer:

\boxed{\text{two}}

Explanation:

In multiplication  and division problems, your answer can have no more significant figures than the number with the fewest significant figures.

\dfrac{7.06 \times 10^{5}}{5.3 \times 10^{-2}}= 1.332 075 472 \times 10^{7} (by my calculator)  

There are three significant figures in 7.06 and two in 2.3.

You must round to \boxed{\textbf{two}} significant figures and report the answer as 1.3 × 1.0⁷.

for number less than 0.1, such as 0.06, the zeros to the right of the decimal point but before the first nonzero digit
qaws [65]

For the number less than 0.1 such as 0.006, the zeroes to the right of the decimal point but before the first non zero digit show the decimal place of the first significant digit.

  • The number that is given as digits is established using significant figures.
  • Any two non-zero digits that are separated by a zero are significant figure.
  • Every zero that is both to the right and left of a non-zero digit and the decimal point is not significant figure.
  • The quantity of significant figures frequently reveals the degree of measurement accuracy. From the first non-zero digits in the figure, we may determine the number of significant figures.

There is only one significant figure in the provided number 0.06. The decimal place of the first digit is indicated by the zeros that appear to the right of the decimal point but before the first non-zero digit.

Combustion of hydrocarbons such as butane (C4H10) produces carbon dioxide, a "greenhouse gas." Greenhouse gases in the Earth's a
sweet-ann [11.9K]

Answer: 2C_4H_{10}(g)+13O_2(g)\rightarrow 8CO_2(g)+10H_2O(g)

Explanation

Combustion is a chemical reaction in which hydrocarbons are burnt in the presence of oxygen to give carbon dioxide and water.

According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.

The balanced combustion reaction for butane is,:

2C_4H_{10}(g)+13O_2(g)\rightarrow 8CO_2(g)+10H_2O(g)
