Answer:
0.24%
Explanation:
The following data were obtained from the question:
Measured value = 42.1 g
Actual value = 42 g
Percentage error =?
Percentage error can be obtained by using the following formula:
Percentage error = |Measured value – Actual value | / Actual value × 100
With the above formula, we can obtain the percentage error as follow:
Measured value = 42.1 g
Actual value = 42 g
Percentage error =?
Percentage error = |42.1 – 42| / 42 × 100
Percentage error = 0.1/42 × 100
Percentage error = 10/42
Percentage error = 0.24%
Therefore, the percentage error is 0.24%
Each different species of grass grows best in a particular grassland environment (determined by temperature, rainfall, and soil conditions). The seasonal drought, occasional fires, and grazing by large mammals all prevent woody shrubs and trees from invading and becoming established.

Answer:
Ok:
Explanation:
So, you can use the Henderson-Hasselbalch equation for this:
pH = pKa + log(
) where A- is the conjugate base of the acid. In other words, A- is the deprotonated form and HA is the protonated.
We can solve that
1 = log(
) and so 10 = or 10HA = A-. For every 1 protonated form of adenosine (HA), there are 10 A-. So, the percent in the protonated form will be 1(1+10) or 1/11 which is close to 9 percent.
6.6 × 
J = 6.2 × 
British thermal units
First of all, we should know that 1 British thermal unit = 1055 Joules.
From question, heat = 6.6 × J
1 BTU = 1055 J
6.6 × J = 
× 6.6 × British thermal units
= 6.2 × British thermal units
1000 Joules = 1 kilojoule
A kilojoule is a unit of measure of energy, in the equal way that kilometers degree distance. meals energy used to be measured in energy and some international locations still use those gadgets.
The power we get from foods and drinks is measured in kilojoules. that is the metric time period for calorie. Kilojoules and energy constitute the equal aspect. One calorie is ready four kilojoules.
Calorie a unit for measuring warmth same to the quantity of warmth required to elevate the temperature of one gram of water one diploma Celsius.
