I think the answer is codominant??
Step 1: write the equation:
P₄(s) + 6F₂(g) → 4PF₃(g)
Step 2: Molar mass of P₄ = 30.97 g/mol × 4 = 123.88 g/mol
Step 3: Number of moles of phosphorus
n = m/M
n = 8.5 g/123.88g/mol
n = 0.07 moles
Step 4: 0.07 × 12 = 0.84 moles of fluorine.
Fluorine is diatomic gas so we multiplied the number of moles by 12.
Step 5: To find the mass of fluorine we multiply the number of moles with the molar mass.
Mass of fluorine = 0.84 × 228
= 191.52 grams.
Answer:
there are three significant digits.
Explanation:
Thus, 21.8, 0.283 and 567 all have three significant digits. 2. Zeros appearing between non-zero digits are significant. Thus, 505 and 0.206 have three significant digits, while 50,005 has five significant digits. (from google)
Answer:
To a certain extent absolutly. They can impact human health for the worse and more.
Answer:
-The stronger electrostatic forces of attraction between the oppositely charged ions causes the Sodium chloride to break apart until it completely dissolves in the water.
Explanation:
-Sodium Chloride has positively charged sodium ions,
and negatively charged chloride ions,
.
-Water on the other hand has positively charged Hydrogen ions,
and negatively charged Oxygen ions,
due to the difference in electroneganivity.
-When dissolved in water, the positively charged sodium ions will attract the partially negatively charged oxygen ions. The negatively charged chloride ions will be attracted to the positively charged hydrogen ions in the reaction as below:
