Answer:
It will be higher in the summer.
Explanation:
Usually, the winter season is more harsh a weather on leaves than summer because it is wet season and thus has less sunlight and this means there will be less photosynthesis reactions and therefore it means the partial pressure will be lesser here unlike in the summer when it is a more warm and dry weather with sunlight where photosynthesis reactions will be more favorable to occur.
Thus, CO2 which is a great component of photosynthesis is used more in the summer and as such the partial pressure in the summer will be higher.
A report on the various water conservation methods used by any one
states of India
Answer:
Kuls are diversion channels that carry water from a glacier to village. Often spanning long distances, with some over 10 km long, kuls have been around for centuries. They are the lifeline of people of Spiti valley of Himachal Pradesh and in Jammu too.
Kul starts at the glacier, which is to be tapped. Keeping the head clear of debris is achieved by lining the sides of Kul with stones which ensure that there is no seepage or clogging. The Kul leads to the village where the water is stored in a circular water tank. The water is drawn from here are per the need of the village.
Explanation:
Here is a list of some of the traditional water conservation methods that are still in use:
What is the freezing point in °C) of a 0.743 m
aqueous solution of KCI?
Enter your rounded answer with
3 decimal places.
K; for water = 1.86 °C/m
Answer:
2.764 °C
Explanation:
ΔT = 2 x 1.86 C/m x 0.743m = 2.764C That means the freezing point of the solution is 2.764C less than the pure solvent (water)
calculate the mass of magnesium needed to make 25g of magnesium oxide
Explanation:
here's the answer to your question about
calculate the maximum mass of ethanol that could be obtained from 30.0g of glucose
Answer:
15.3g
Explanation:
C6H12O6 → 2C2H5OH + 2CO2
1 mol C6H12O6 = 180g
1 mol CH3-CH2-OH = 46g
From 180g glucose ethanol can get = 92g
30g glucose ethanol gives us = (92*30)/180 = 15.33g

Which element will form In ion whose lonic radius is larger than its atomic radius?
(1) K
(2) F
(3) LI
(4) Mg
Answer:
Letter b so F
Explanation:
I hope this help
Explanation:
All five ions have an equal number of electrons and therefore share the same electron configuration. For example, a neutral calcium atom (Z=20) has 20 electrons; it loses two of them to form a Ca2+ cation, which would thus contain 20−2=18 electrons. Similarly, a phosphorus atom (Z=15) gains three electrons to form a P3− anion that contains 15+3=18 electrons.
Positively-charged protons in the nuclei attract the negatively-charged electron cloud. Each proton carries a +1 charge; the more protons an atom or ion contains the stronger the attraction it poses on its electron cloud. A nucleus of strong positive charge pulls its electron cloud towards itself tightly such that the latter would have a small radius.
The periodic table is arranged in the order of increasing proton number. Phosphorus comes the first among the five species and contains the least number of protons. Its ion would be the largest among the five. Calcium comes the last and forms the smallest ion.

What mass of helium gas (in g) occupies 15.3 L at STP?
Answer:
[tex]\boxed {\boxed {\sf 2.73 \ g \ He}}[/tex]
Explanation:
We are asked to find the mass of helium gas given a volume.
1. Convert Liters to Moles1 mole of any gas occupies a volume of 22.4 liters. So, 1 mole of helium gas contains 22.4 liters of helium. Create a ratio using this information.
[tex]\frac {1 \ mol \ He }{ 22.4 \ L \ He}[/tex]
We are converting 15.3 liters of gas to moles, so we multiply by that value.
[tex]15.3 \ L \ He *\frac {1 \ mol \ He }{ 22.4 \ L \ He}[/tex]
The units of liters of helium (L He) cancel.
[tex]15.3 *\frac {1 \ mol \ He }{ 22.4}[/tex]
[tex]\frac {15.3}{22.4} \ mol \ He[/tex]
[tex]0.6830357143 \ mol \ He[/tex]
2. Convert Moles to GramsThe molar mass is the mass of 1 mole of a substance. These values are found on the Periodic Table as atomic masses, but the units are grams per moles. Look up the molar mass of helium.
He: 4.0026 g/molCreate another ratio using the molar mass.
[tex]\frac {4.0026 \ g \ He}{1 \ mol \ He}[/tex]
Multiply by the number of moles we calculated.
[tex]0.6830357143 \ mol \ He *\frac {4.0026 \ g \ He}{1 \ mol \ He}[/tex]
The units of moles of helium (mol He) cancel.
[tex]0.6830357143*\frac {4.0026 \ g \ He}{1 }[/tex]
[tex]2.73391875 \ g \ He[/tex]
3. RoundThe original measurement of volume has 3 significant figures, so our answer must have the same.
For the number we calculated, that is the hundredths place.
The 3 in the thousandths place to the right (2.73391875) tells us to leave the 3 in the hundredths place (2.73391875).
[tex]2.73 \ g \ He[/tex]
15.3 liters of helium gas is approximately 2.73 grams of helium.
While driving her car on a hot sunny day, a woman was struck in the back of the neck by the dough from an exploding can of Pillsbury biscuits. From the sound it made and the feeling of warm sticky dough on her neck, she thought she had been hit by a bullet! Describe the likely conditions that caused this to happen. Be sure to explain AT THE MICRO scale how the particles were affected.
Answer:
The dough is made from flour sugar, baking soda, sometimes yeast. The sugar is converted into gaseous products including carbon dioxide, CO₂ and alcohols. As more gases are produced, the pressure increases, and according to Charles's law, as the temperature on a sunny day is higher than on a cool day, the pressure of the gases increases further, to the point that the can containing the biscuits can not hold the pressure, leading to an explosion

Explain how the existence of ions relates to the number of electrons present in atoms of an element? (A.P.E.X)
Answer:
if you have options please include them, but I'll give you an idea.
Explanation:
The existence of ions happens when atoms lose or gain electrons.
if an atom gains an electron it will become a negative ion (because electrons are negative, and you gained more negativity.)
if an atom loses an electron it will become a positive ion (because it has lost negativity, which is the electron that we've lost).

For his science fair project, Martin studied the growth of trumpet vines. He grew 20 trumpet vines. All of the conditions were the same, except that he grew 10 in a flower bed without support and 10 in a flower bed near a trellis. The stems of the vines near the trellis twisted around the trellis, and these Yines grew tall and seemed much healthier than the vines grown without a trellis. In fact, four of the vines grown without a trellis died. Which characteristic of living things were the trumpet vines displaying as the stems twisted around the trellis?
A. Movement
B. Response to a stimulus
C. Use of energy
D. Reproduction
Answer:
it's B
Explanation:
Climbing plants require an external support to grow vertically and enhance light acquisition. Vines that find a suitable support have greater performance and fitness than those that remain prostrate. Therefore, the location of a suitable support is a key process in the life history of climbing plants
