Answer : The water's temperature change will be, 
Explanation : Given,
Density of water = 0.998 g/mL
Volume of water = 
(conversion used : 1 L = 1000 mL)
Specific heat of water = 
Heat absorbed = 
(conversion used : 1 kJ = 1000 J)
First we have to determine the mass of water.
Now we have to calculate the change in temperature of water.
Formula used :
where,
Q = heat absorbed by water
m = mass of water
= specific heat of water
= change in temperature
Now put all the given value in the above formula, we get:
Therefore, the water's temperature change will be,
Homogeneous mixture. (all of the different components of the salad are shown)
Cross contamination can be caused by CARRYING DRINKING GLASSES BY THE RIMS.
Cross contamination refers to the transfer of harmful microbes to foods from various sources. The rim of a drinking glass is where you put your mouth when you are drinking from a glass cup. If one is carrying a drinking glass by the rim, one can easily transfer the dirty in one's hand to the glass and this will be ingested by person who use the cup. Drinking glasses should be carried by holding their bases.
Answer:
Explanation:
Hello,
In this case, the undergoing balanced chemical reaction is:
Thus, as 5.22 grams of aluminium oxide reacts, the required yielded amount of aluminium sulfate results:
Moreover, the percent yield is:
Best regards.
Answer:
0.591 g of magnesium phosphate is the theoretical yield.
Magnesium nitrate is the limiting reactant.
Explanation:
Hello!
In this case, since the balanced reaction turns out:
Next, we compute the grams of magnesium phosphate yielded by each reactant, considering the present mole ratios and molar masses:
Thus, we infer that the correct theoretical yielded mass is 0.591 g as magnesium nitrate is the limiting reactant for which it produces the fewest grams of product.
However, is not possible to compute the percent yield since no actual yield is given, and must be provided or indicated by the problem or an experiment and it not here, nevertheless, you may compute the percent yield by dividing the actual yield by the theoretical and then multiplying by 100:
Best regards!
