Answer:
2450 cm3
Explanation:
Volume of cylinder = V=πr2h
2.45L = 2450mL
1mL = 1 cm cubed
2450mL = 2450 cm cubed
<h3>
Answer:</h3>
The products of the reaction are; AgCl and NaNO₃
<h3>
Explanation:</h3>
In this question we need to know what is a double displacement reaction;
- A double displacement is a type of replacement reaction in which salts or ionic compounds exchange cations and anions to form new compounds as the products.
- In this case, the complete double replacement reaction is;
AgNO₃(aq) + NaCl(aq) → AgCl(s) + NaNO₃(aq)
- The reaction is also a precipitation reaction as it forms a precipitate as one of the products that is silver chloride (AgCl).
- Therefore, the products of the reaction are; AgCl and NaNO₃
Answer: C (The first species to populate an uninhabited area)
Explanation:
Answer:
Molarity = 54.50 M
Explanation:
Molarity is defined as the number of moles of a solute in 1 liter of solution. It has mol/l unit.
Molar mass of glucose, C6H12O6 = (6*12) + (1*12) + (16*6)
= 72 + 12 + 96 = 180g/mol
Density of glucose solution = 1.03g/ml
Density in g/l = 1.03g/ml * 1ml/10^-3l
= 1030g/l
10.5% mass of glucose = 10.5/100 * 180
= 18.9g/mol
Molarity = density (g/l)/molar mass (g/mol)
= 1030/18.9
= 54.50 M
A catalyst increases the rate of a chemical reaction, as a sub category, an enzyme also preforms the same job.
