Answer:

151200 minutes.

Explanation:

From the question given above, the following data were obtained:

Time (in week) = 15 weeks

Time (in min) =?

Next, we shall convert 15 weeks to days. This can be obtained as follow:

1 week = 7 days

Therefore,

15 weeks = 15 weeks × 7 days / 1 week

15 weeks = 105 days

Next, we shall convert 105 days to hours. This can be obtained as follow:

1 day = 24 h

Therefore,

105 days = 105 days × 24 h / 1 day

105 days = 2520 h

Finally, we shall convert 2520 h to mins. This can be obtained as follow:

1 h = 60 mins

Therefore,

2520 h = 2520 h × 60 mins / 1 h

2520 h = 151200 mins

Thus, 15 weeks is equivalent to 151200 minutes.

Identify the following salts as neutral, acidic, or basic.
allochka39001 [22]

Answer:

1)NH4ClO4: acidic

2)NH4CN: basic

3)LiF: basic

4)KCN: basic

5)LiNO3: neutral

6)NH4Br: acidic

7)SrBr2: neutral

Explanation:

Salt is an ionic compound formed by the neutralization reaction between an acid and a base.The cation of base and anion from an acid combines to form a salt while H+ from acid and OH- from base forms water.

1)NH4Cl4: is an acidic salt formed from neutralization reaction between strong acid and a weak base.

2)NH4CN: is a basic salt formed from neutralization reaction between weak acid and weak base.

3)LiF: basic salt formed from neutralization reaction between strong acid and strong base.

4)KCN: basic salt formed from neutralization reaction between weak acid and strong base.

5)LiNO3: neutral salt formed from neutralization reaction between strong acid and strong base.

6)NH4Br: acidic salt formed from neutralization reaction between strong acid and weak base.

7)SrBr2: neutral acid formed from neutralization reaction between

strong acid and strong base.

Determine the mass number of an element that contains 26 protons, 22 electrons, and 30 neurons
Cloud [144]

Answer:

56 is the mass

Explanation:

You would add 26 and 30(the protons and neutrons). I didn't add the electrons because they are so small their mass is negligible in this situation.
