Answer:
i only know 6 whitch is the +ion
Explanation:
1.55 g/L; 9.503 03 × 10^20 mL
<em>Part 1.
</em>
<em>Step 1</em>. Convert <em>kilograms to grams</em>.
1.55 kg × (1000 g/1 kg) = 1550 g
<em>Step 2</em>. Convert <em>cubic metres to litres</em>.
1 m^3 × (1000 L/1 m^3) = 1000 L
<em>Step 3</em>. Divide <em>grams by litres</em>
1.55 kg/1 m^3 = 1550 g/1000 L = 1.55 g/L
<em>Part 2.</em>
<em>Step 1</em>. Convert <em>cubic kilometres to cubic metres</em>
950 303 km^3 × (1000 m/1 km)^3 = 9.503 03 × 10^14 m^3
<em>Step 2</em>. Convert <em>cubic metres to litres</em>.
9.503 03 × 10^14 m^3 × (1000 L/1 m^3) = 9.503 03 × 10^17 L
<em>Step 3</em>. Convert <em>litres to millilitres</em>.
9.503 03 × 10^17 L × (1000 mL/1 mL) = 9.503 03 × 10^20 mL
To satisfy the law of conservation of mass
2C4H10 + 13O2 Right arrow. 8CO2 + 10H2O
What is the mole ratio of butane to carbon dioxide?
ANSWER:
Butane is an organic compound with the formula C4H10 and carbon dioxide is compound (gas) with the formula CO2. So, the balanced coefficient of butane is 2, and that of carbon dioxide is 8. According to thid, the mole ratio of butane to carbon dioxide is 2:8 or 1:4.
