or
% m/v = g solute / 100 ml solution
Concentration : 2 g sodium borate / L water
For 10 L⇒20 g Sodium borate
Answer: The answer is C- comets!
Explanation: Callisto is composed mainly of rock and water ice, although other ices like ammonia ice and carbon dioxide ice may be present. Water ice occurs at the surface of Callisto so it would be comets.
Answer:
The Coriolis effect is caused by the rotation of the earth around its own axis.
Explanation:
The Coriolis effect arises from the fact that different latitudes of the earth's surface rotate at different speeds. The path of wind on earth is deflected by the Coriolis effect. As things move over the earth, they meet different speed areas, which causes the Coriolis Effect to divert their route.
Thus, The Coriolis effect is caused by the rotation of the earth around its own axis.
The formula that denotes the incomplete combustion of carbon in the presence of a limited amount of oxygen is <span>2 C + O</span>₂<span> → 2 CO
If the mass of oxygen that is used to combust carbon is 35 g
then the moles of oxygen = mass of oxygen </span>÷ molar mass of oxygen
= 35 g ÷ 32 g/mol
= 1.0938 mol
Now, the mole ratio of oxygen : carbon monoxide based on the balance equation is 1 : 2
⇒ If the mole of oxygen = 1.0938 mol
then the mole of carbon monoxide = 1.0938 × 2
= 2.1876 mol
Mass of CO is = mol of CO × molar mass of CO
= 2.1876 mol × 28 g/mol
= 61.25 g
∴ when a certain mass of carbon is combusted in 35g of oxygen then it produces approx. 61.25 g of Carbon Monoxide.
