Answer:
121.63 g/mol
Explanation:
Sr(OH) 2 = Strontium Hydroxide
Answer:
2
Explanation:
Data:
[H⁺] = 0.01 mol·L⁻¹
Calculation:
pH = -log[H₃O⁺] = -log(0.01) = -log(1) - log(10⁻²) = -0 - (-2) = 0 + 2 = 2
Answer:
Two electrons each!
Explanation:
The question pretty much requires us to find the oxidation number of Zinc in the compound.
Zn3P2
Following oxidation number rules;
O.N of Zn3P2 = 0
.Since phosphorus has valence of 5, it needs three more electrons to achieve its octet state. Hence;
Oxidation number of P = -3
Let oxidation number of Zn = x
We have;
3x + 2 (-3) = 0
3x + (-6) = 0
3x = 6
x = 6/3 = 2
This means each zn electrons lost 2 electrons.
The specific proteins produced by cell B in response to the foreign substance are antibodies.
<h3>What are antibodies?</h3>
Antibodies are specific proteins produced by the immune cells of the body in response to a foreign substance called antigen which produces the immune response.
Antibodies are released by immune cells such as B cells.
The antibodies bind to antigen and tag them for destruction by phagocytes.
Therefore, cell B will produce antibodies.
