Because sucrase will react with product and lower his concentration, so measurement of product concentration will not be accurate.
Sucrase activity is greater when sucrose concentration went from 2.5 to 7.5 g/l, because difference (increase<span>) between two concentration (numbers) is greater.</span>
Answer:
Homogeneous mixtures mix completely but heterogeneous mixtures don't mix completely
1) One piece of science equipment that you might not have been introduced to is the graduated cylinder. measure volume of a liquid.
2) Although you need to be careful when using a Bunsen burner, I think it is one of the most interesting lab tools to use. A Bunsen burner is a heat source used to raise the temperature.
Answer:
3.89 kg P2O5 must be used to supply 1.69 kg Phosphorus to the soil.
Explanation:
The molecular mass of P2O5 is
P2 = 2* 31 = 62
O5 = 5 *<u> 16 = 80</u>
Molecular Mass = 142
Set up a Proportion
142 grams P2O5 supplies 62 grams of phosphorus
x kg P2O5 supplies 1.69 kg of phosphorus
Though this might be a bit anti intuitive, you don't have to convert the units for this question. The ratio is all that is important.
142/x = 62/1.69 Cross multiply
142 * 1.69 = 62x combine the left
239.98 = 62x Divide by 62
239.98/62 = x
3.89 kg of P2O5 must be used.
