Non metals can not give electrons to hydrogen in water to be released as H2 gas
Step 1. - Scientists first take a look at their empirical evidence and try to explain it.
Step 2. - Scientists test if their explanation or conclusion is logical.
Step 3. - If their explanation is logical, they search for new test that may help them to support their first idea.
Answer:
32.0 kJ
General Formulas and Concepts:
<u>Thermochemistry</u>
Specific Heat Formula: q = mcΔT
- q is heat (in J)
- m is mass (in g)
- c is specific heat (in J/g °C)
- ΔT is change in temperature (in °C)
Explanation:
<u>Step 1: Define</u>
<em>Identify variables</em>
[Given] <em>m</em> = 1.00 g
[Given] ΔT = 1.48 °C
[Given] <em>c</em> = 21.6 kJ/g °C
[Solve] <em>q</em>
<em />
<u>Step 2: Find Heat</u>
- Substitute in variables [Specific Heat Formula]: q = (1.00 g)(21.6 kJ/g °C)(1.48 °C)
- Multiply [Cancel out units]: q = (21.6 kJ/°C)(1.48 °C)
- Multiply [Cancel out units]: q = 31.968 kJ
<u>Step 3: Check</u>
<em>Follow sig fig rules and round. We are given 3 sig figs.</em>
31.968 kJ ≈ 32.0 kJ
Answer:
Meiosis produces haploid cells (gametes), which contain single chromosomes, or on-half the number of chromosomes in diploid cells. When a sperm and an egg join, the single chromosomes pair up, which results in genetic diversity in the offspring
It's an Arrhenius acid and increases the concentration of H+ in water and creates H3O+ ions.
