Answer:
10mL
Explanation:
Using the formula as follows:
CaVa = CbVb
Where;
Ca = concentration of acid, HBr (M)
Cb = concentration of base, Sr(OH)2 (M)
Va = volume of acid, HBr (Litres)
Vb = volume of base, Sr(OH)2 (Litres)
According to the information given in this question;
Ca = 0.24M
Cb = 0.24M
Va = ?
Vb = 10.0ml
Using CaVa = CbVb
0.24 × Va = 0.24 × 10
0.24Va = 2.4
Va = 2.4 ÷ 0.24
Va = 10mL
10mL of HBr is needed.
Answer:
1s² 2s² 2p⁶ 3s² 3p⁴
Explanation:
Looking at the <em>periodic table</em>, we see that sulfur (S) has an atomic number of 16, this means its electronic configuration would be:
We know the electronic configuration written above is correct because the sum of all the superscript numbers is 16 (2+2+6+3+4=16).
The answer is compost. It is an organic
matter that has been disintegrated and cast-off as fertilizer and soil
alteration. This is a significant component in organic
farming. The procedure of composting necessitates creating a mound of wet
organic substance identified as green wastes – these are leaves, food
waste and waiting for the resources to collapse into humus after
weeks or months.
