Answer:
The acid in the soil
Explanation:
The more acid the bluer in terms of hydrangea flowers if there was a balance between the two it will be half and half of the two colors.
Answer:
![V_2=12.1L](https://tex.z-dn.net/?f=V_2%3D12.1L)
Explanation:
Hello!
In this case, according to the given data of volume, pressure and temperature, it is possible to infer this problem can be solved via the combined gas law:
![\frac{P_1V_1}{T_1} =\frac{P_2V_2}{T_2}](https://tex.z-dn.net/?f=%5Cfrac%7BP_1V_1%7D%7BT_1%7D%20%3D%5Cfrac%7BP_2V_2%7D%7BT_2%7D)
Thus, regarding the question, we evidence we need V2, but first we make sure the temperatures are in Kelvins:
![T_1=20+273=293K\\\\T_2=-40+273=233K](https://tex.z-dn.net/?f=T_1%3D20%2B273%3D293K%5C%5C%5C%5CT_2%3D-40%2B273%3D233K)
Then, we obtain:
![V_2=\frac{P_1V_1T_2}{T_1P_2}\\\\V_2=\frac{0.987atm*8.50L*233K}{293K*0.550atm}\\\\V_2=12.1L](https://tex.z-dn.net/?f=V_2%3D%5Cfrac%7BP_1V_1T_2%7D%7BT_1P_2%7D%5C%5C%5C%5CV_2%3D%5Cfrac%7B0.987atm%2A8.50L%2A233K%7D%7B293K%2A0.550atm%7D%5C%5C%5C%5CV_2%3D12.1L)
Best regards!

Answer:
D. H₂SO₄
Explanation:
Bronsted acids are those that donate H+ ions. In this question, H₂SO₄ is a Bronsted acid.
Note: H₂SO₄ is one of seven strong acids that you should try to memorize.
Answer: Option (E) is the correct answer.
Explanation:
When we move from top to bottom in a group then there occurs an increase in atomic size of the atoms due to increase in the number of electrons.
For example, in group 2A elements beryllium is the smallest in size whereas radium being at the bottom is the largest in size.
Also, atomic number of beryllium is 4 and atomic number of radium is 88.
Thus, we can conclude that out of the given options radium is the 2A element which has the largest atomic radius.
