Answer:
333g/L
Explanation:
The moles of CaCl2 in 6mEq are:
6mEq * (1mmol / 2mEq) = 3mmol CaCl2.
<em>2Eq / mol because the charge of Ca is 2+</em>
<em />
The mass is:
3mmol CaCl2 * (111mg/mmol) = 333mg = 0.333g
<em>Molar mass: 2*35.5g/mol + 40g/mol = 111g/mol = 111mg/mmol</em>
The liters are:
1mL * (1L / 1000mL) = 1x10⁻³L
The concentration in grams per liter is:
0.333g / 1x10⁻³L = 333g/L
Answer:
Electronic configuration of nitrogen: K=2 L=5
Electronic configuration of phosphorus : K = 2 L = 8 M = 5
The element nitrogen will be more electronegative because of the smaller size of its atom. nitrogen accepts electrons more easily.
Explanation:
I think it’s Agci the answer
Elements that are found in potassium oxide is oxygen.
Al2so4+NaOH =Naso4+AlOH= so I think it’s B not sure
