Based on the graph, the statement that is most likely
correct about the periods 1800 to 1850 and 1900 to 1950 is that there was decrease in global temperatures. The
answer is letter B. The rest of the choices does not fit tot the description of
the graph.
Answer:
4.9 x 10⁻⁶.
Explanation:
<em>2H₂O(g) ⇄ 2H₂(g) + O₂(g),</em>
'
P of H₂ = 0.002 atm, P of O₂ = 0.006 atm, and P of H₂O = 0.07 atm.
∴ The equilibrium constant (Kp) = (P of H₂)²(P of O₂)/(P of H₂O)² = (0.002 atm)²(0.006 atm)/(0.07 atm)² = 4.9 x 10⁻⁶.

<u>
CF4 </u>
is the one which is covalent compound</h2><h2 /><h2 /><h2>explanation</h2>
CF4 compound is formed between two non metal that is between carbon and fluorine and a covalent compound is formed when two non metal combine by sharing. electrons. CF4 has a strong bond strength due to the nature of carbon- fluorine bond.
The question is incomplete. Complete question is read as:
'<span>One cup of fresh orange juice contains 115 mg of ascorbic acid (vitamin C, C6H8O6). Given that one cup = 218.0 mL calculate the molarity of vitamin C in organic juice.'
..........................................................................................................................
Answer:
Given: weight of solute (ascorbic acid) = 115 mg = 0.115 g
Volume of solution = 218.0 mL = 0.218 L
Molecular weight of ascorbic acid = 176.12 g/mol.
Now, Molarity = </span>

=

<span> =
0.002995 mol/dm3Answer: Molarity of solution = </span>
0.002995 mol/dm3<span>
</span>
Answer:
Explanation:
conjugate acid, based on Brønsted–Lowry acid–base theory, is a chemical compound that is formed by the reception of a proton by a base
a. CH₃COOH + H₂O ⇌ H₃0⁺ + CH₃C00-
Acid <> CH₃COOH
Base <> H₂O
Conjugate acid <> H₃0 +
Conjugate base <>CH₃C00-
b. HCO₃ + H₂O ⇌ H₂CO₃⁻ + OH⁻
Acid <> H₂O
Base <> HCO₃
Conjugate acid <> H₂CO₃⁻
Conjugate base <>OH⁻
C. HNO₃ + SO₄²⁻ ⇌ HSO₄⁻ + NO₃⁻
Acid <>HNO₃
Base <>SO₄²⁻
Conjugate acid <>HSO₄⁻
Conjugate base <>NO₃⁻
A Bronsted acid is reffered to as a proton donor while a Bronsted base is a proton acceptor
