Answer: option A
Explanation: Organic chemistry deals with the study of carbon and hydrogen containing compounds, drugs and pharmaceuticals etc.
Answer:
glucose and galactose
concentration of the enzyme
temperature and pH
glucose and galactose
Explanation:
Enzymes are biological catalysts. They catalyze various biochemical reactions in the body. Enzymes are proteins.
The enzyme responsible for the breakdown of lactose is lactase. This enzyme catalyzes the breakdown of lactose to glucose and galactose. Galactose is about 65% as sweet as sucrose.
The rate of enzyme reaction is influenced by the concentration of the enzyme. As the concentration of the enzyme is increased, the velocity of the reaction proportionately increases.
Temperature and pH are important environmental factors that affect the rate of enzyme catalyzed reaction because they influence the activity of the enzyme and may even denature the enzyme.
Answer:
Explanation:
I'm not sure what is being asked, not the units of "1.5." I don't know of potassium "ioxicide." Was "dioxide" intended?
I'll assume the question is "What is the concentration, in Molar, of 1.5g of potassium dioxide in 150cm^3 of water (150cm^3 is 150 ml).
The molar mass of K2O, potassium dioxide, is 94.2 g/mole. 1.5g is (1.5g/94.2 g/mole) or 0.0159 moles of K2O. The definition of Molar is moles/liter. So take the moles of K2O and divide by the liters, which is 0.150L in this case.
(0.0159 moles K2)/0.150 L = 0.106 M K2O
Answer:
D. section of DNA that codes for a specific trait
Explanation:
Genes are sections of the DNA that codes for a specific trait. They are simply defined as the basic physical and functional unit of hereditary.
- Genes are usually found encoded in the DNA.
- The effects produced by genes result from their coordination of certain protein synthesis activities.
- Inheritance is attained when genes are passed from parents to offspring.
Answer:
20 g Ag
General Formulas and Concepts:
<u>Chemistry - Stoichiometry</u>
- Using Dimensional Analysis
<u>Chemistry - Atomic Structure</u>
Explanation:
<u>Step 1: Define</u>
[RxN] Cu (s) + AgNO₃ (aq) → CuNO₃ (aq) + Ag (s)
[Given] 10 g Cu
<u>Step 2: Identify Conversions</u>
[RxN] 1 mol Cu = 1 mol Ag
Molar Mass of Cu - 63.55 g/mol
Molar Mass of Ag - 197.87 g/mol
<u>Step 3: Stoichiometry</u>
<u />
= 16.974 g Ag
<u>Step 4: Check</u>
<em>We are given 1 sig fig. Follow sig fig rules and round.</em>
16.974 g Ag ≈ 20 g Ag
