The phenomenon is known as the Greenhouse Effect.
When the sun's energy reaches the Earth, some is reflected into space, but the rest is absorbed by gases and warms the atmosphere. The phenomenon is known as the Greenhouse Effect.
One mole of copper equals 6.02 × 10^23 atoms. The answer is letter C. This follows the
Avogaro’s law wherein 1 mole of a substance is equal to 6.02 x 10^23 atoms,
formula units or molecules. This is applicable to all substances.
Answer:
The median would be 6700
Explanation:
Arrange data values from lowest to highest value
The median is the data value in the middle of the set
.
Ordering a data set x1 ≤ x2 ≤ x3 ≤ ... ≤ xn from lowest to highest value, the median x˜ is the data point separating the upper half of the data values from the lower half.
If the size of the data set n is odd the median is the value at position p where
Formula for the median
p=n+12
x˜=xp
If n is even the median is the average of the values at positions p and p + 1 where
p=n2
x˜=xp+xp+12
If there are 2 data values in the middle the median is the mean of those 2 values.
Answer: Crocodiles and tigers both have four legs
Explanation: Even when sharks and tigers are both meat eaters, the question is about similarities between tigers and crocodiles, so D is out. A is about crocodiles and sharks, so it's out also. B suits for sharks too, so it's out too. C is the most suitable answer, because both animals have four legs, which means that they belong to the group of quadrupede animals.
Answer:a) 2C4H10 + 13O2 —> 8CO2 + 10H2O. Oxidation reaction
b) 8 (4 moles CO2 per mole butane)
Explanation:
could be written C4H10 + 6 1/2 O2 —> 4CO2 + 5H2O
