Answer:
Risk management can be described as the identification and evaluation of certain risks beforehand and the appropriate steps that can be taken to avoid the problematic situations. Risk management is the forecasting of certain risks and the plans made to resist or overcome these risk situations.
An example of a risk management strategy can be a pet owner understanding that he'll have to make major payments for the health of the pet or will have to pay vet bills. In order to save money, the pet owner decided to go for pet insurance beforehand so that any problematic situation can be avoided.
Answer:
magnesium= +2
aluminum= +3
phosphorous= -3
lithium= +1
fluorine= -1
Explanation:
As fluorine having seven valance electrons in its outer most shell with atomic number nine. And for completing its outer most shell it needs one more electron that is why it form ion of -1 value.
Now Aluminum has three electrons in its outer most shell with atomic number 13. So it need to lose these three electrons in order to be in stable state that is why it have ion in +3 state.
Same rule apply for other elements too.
Answer:- 537 kJ of heat is released.
Solution:- For the given equation, 
is -657 kJ and the coefficient of 
in the balanced equation is 2. It means 657 kJ of heat is released when 2 moles of chlorine are used. We need to calculate the heat released when 116 g of are used.
Grams of chlorine are converted to moles and then multiplied by the value and divided by the coefficient of chlorine and the set could be shown using dimensional analysis as:
= 537.46 kJ
If we use the correct sig figs then it needs to be round off to three sig figs as the given grams of chlorine has only three sig figs. So, 537 kJ of heat is released.
Answer:
The answer to your question is 1.013 Kg
Explanation:
TiCl₄ + 2Mg ⇒ 2MgCl₂ + Ti
mass of Mg = ?
mass of Ti = 1 kg
Process
1.- Calculate the molar mass of Magnesium and titanium (IV)
Mg = 24.3 g x 2 = 48.6 g
Ti = 48 g
2.- Write a proportion (rule of three)
48.6 g of Mg ------------- 48 g of Ti
x ------------- 1000 g of Ti
x = (1000 x 48.6) / 48
3.- Result
mass of Magnesium = 1012.5g
= 1.013 kg
