Always use least amount of sig figs possible. So this 9.7 would be (answer): 2 sig figs
There are different kinds of reactions. To name some, these are the synthesis reaction, decomposition reaction, single-replacement reaction, double-replacement reaction, combustion reaction, redox reaction, etc. For this type of reaction involving two reactants to yield only one product, <em>this is a synthesis reaction.</em>
<em>P₄ (s) + 6 Ca (s) --> 2 Ca₃P₂ (s)</em>
Toluene is aromatic organic compound and is derived from benzene by substituting on H with methyl group. The molecular formula of Toluene is C₇H₈.
When Toluene is subjected to combustion reaction it produces carbon dioxide and water. The balance chemical reaction for combustion of toluene is as follow,
C₇H₈ + 9 O₂ → 7 CO₂ + 4 H₂O
Answer:
Explanation:
<u>1) Data:</u>
a) V = 500.0 ml = 0.500 liter
b) M = 0.100
c) mass = ?
<u>2) Formulae:</u>
a) Molarity: M = n / V
b) Number of moles: n = mass in grams / molar mass
<u>3) Solution</u>
a) M = n / V ⇒ n = M × V = 0.1000 M × 0.500 liter = 0.0500 mol
b) molar mass NaCl = 58.443 g/mol
c) mass = n × molar mass = 0.0500 mol × 58.443 g/mol = 2.92 g
Answer: 2.92 g
