In the systemic arteries, the partial pressure of carbon dioxide is 40 mm Hg. Partial pressure of a gas is the contribution of one gas to the total pressure exerted by all gases. Partial pressure of carbon dioxide in arterial blood is the portion of total blood gas pressure that is exerted by carbon dioxide. It decreases during heavy exercise, during rapid breathing, or in association with severe diarrhea, uncontrolled diabetes or the diseases of the kidney. It increases with chest injuries and respiratory disorders. In the systemic arteries, the partial pressure of oxygen is 100 mm Hg.
Answer:
Reduced, alkane
Explanation:
Wolf-Kishner reaction is a type of reduction reaction in which aldehydes and ketones are reduced to their corresponding alkane in the presence of a base.
This reaction occurs at high temperature.
Alkane formed has a same number of carbon as aldehyde and ketone.
If acetaldehyde undergoes a Wolf-Kishner reaction in the presence of base and heat, then ethane is formed. Nitrogen is formed as a byproduct.
Here, acetaldehyde is reduced to form ethane.
So, acetaldehyde undergoes a Wolf-Kishner reaction, which is the addition of hydrazine with subsequent addition of a base and heat. In this reaction, the aldehyde is reduced, resulting in alkane product.
Answer:
Honey is an homogeneous mixture
Salsa is an heterogeneous mixture
Explanation:
Honey is a sweet uniformly colored liquid that can be of a dark variety or of clear golden color. Honey is made in nature by bees from flower nectar and is used as a food additive or sweetener
Honey is a homogeneous mixture because the concentration of the components of honey are uniformly distributed throughout the mixture. Every portion has the same concentration of components
Salsa is a sauce made by mixing chopped tomatoes, onions, chilies, lime juice and seasoning and therefore consists of both solid and liquid components mixed in varying proportion such that part will have continuous that comes in between different types of solid and no two parts have exactly the same composition
Therefore, salsa is an heterogenous liquid.
Answer:
The two products that will be formed are:
Ca(NO3)2
NaI
Explanation:
When NaNO3 reacts with CaI2, double substitution reaction takes place.
This means that I2 and NO3 will each substitute the other.
The chemical reaction used to explain this is as follows:
2NaNO3 + CaI2 .........> 2NaI + Ca(NO3)2
Hope this helps :)
Answer:
2.4 dm-3
Explanation:
Equation of the reaction;
2HCl(aq) + Ba(OH)2(aq) -------> BaCl2(aq) + 2 H2O(l)
Volume of acid VA = ??
Concentration of acid CA = 0.25 moldm-3
Volume of base VB = 2.0 dm^3
Concentration of base CB = 0.15 moldm-3
Number of moles of acid NA = 2
Number of moles of base NB = 1
CAVA/CBVB = NA/NB
CAVANB = CBVBNA
VA = CBVBNA/CANB
VA = 0.15 * 2 * 2/0.25 *1
VA = 2.4 dm-3
