what does the changing the Aperture do when taking a photo? *
4.What effect can you get from using a slow shutter speed? *
5.What effect can you create by using a quick shutter speed
Answer:
Slower shutter speeds like 1/60 second and slower cause a blurring effect. If you want to take a picture using a slow shutter speed, it is best to mount the camera on a tripod and use image stabilization (such as SteadyShot® technology) to reduce the chance of any unwanted camera movement.
The first big effect of it is motion blur. If your shutter speed is long, moving subjects in your photo will appear blurred along the direction of motion. ... If you use an especially fast shutter speed, you can eliminate motion even from fast-moving objects, like birds in flight, or cars driving past.

How many mL of O2 at STP are produced from 1.5 g KClO3
Answer:
64.2 L
i watch videos about this stuff because my grades were very low now im bringing the up
Explanation:
In order to be able to calculate the volume of oxygen gas produced by this reaction, you need to know the conditions for pressure and temperature.
Since no mention of those conditions was made, I'll assume that the reaction takes place at STP, Standard Temperature and Pressure.
STP conditions are defined as a pressure of
100 kPa
and a temperature of 0∘C
. Under these conditions for pressure and temperature, one mole of any ideal gas occupies
22.7 L
- this is known as the molar volume of a gas at STP.
So, in order to find the volume of oxygen gas at STP, you need to know how many moles of oxygen are produced by this reaction.
The balanced chemical equation for this decomposition reaction looks like this
2KClO3(s]heat×−−−→2KCl(s]+3O2(g]↑⏐
How many molecules of glucose (C6H12O6,M=180.18g/mol) are contained in 144mL of 0.280 M glucose solution?
Volume of Glucose solution = 144 mL OR 0.144 L
Molarity of Glucose solution = 0.280 M
Number of moles of Glucose in the solution:From the definition of Molarity, we know that:
Molarity = number of moles / volume(in L)
in this equation, multiplying both sides by Volume, we get:
number of moles = Molarity*Volume(in L)
replacing the variables
Number of moles = 0.280*(0.144L)
Number of moles = 0.04
Number of Molecules in the solution:
We know that:
Number of molecules = Number of Moles * Avogadro's number
Number of molecules = 0.04 * 6.022 * 10²³
Number of molecules = 0.24088 * 10²³
Number of molecules = 2.4088 * 10²²
Therefore, there are 2.4088 * 10²² molecules of Glucose in the given solution

The percent by mass of Ca in CaCl[tex]_2[/tex] is equal to (40/111) x 100. The correct option is option A.
What is percentage by mass?Mass percentage represents the the percentage of each element that is making a particular compound.
Mathematically,
Percentage of mass = (component’s mass ÷ total mass) x 100%
Atomic weight of different element of calcium chloride{ CaCl[tex]_2[/tex]} are
Ca = 40 ; Cl = 35
Total mass of Calcium element in calcium chloride = 40g/mol
Total mass of Chlorine atom in calcium chloride = 35× 2= 71g/mol
Total molar mass of calcium phosphate = 40 +71= 111g/mole
Percentage of calcium in calcium chloride =40÷111 = 36%
Therefore, the percent by mass of Ca in CaCl2 is equal to (40/111) x 100. The correct option is option A.

Copper(I) complexes tend to be tetrahedral rather than octahedral or square planar. Why is this the case? Explain your reasoning.
Answer:
The ion is d^10
Explanation:
Tetrahedral geometry is one in which the central atom/ion is located at the center of four ligands positioned at the corners of a tetrahedron.
It is different from a square planar complex wherein the ligands are positioned at the corners of a square with the central atom/ion at the center of the square.
Tetrahedral complexes are more common with d^10 species.The electronic configuration of Cu I is [Ar]3d104s1. Hence, a tetrahedral geometry is preferred over a square planar geometry.

Magnesium bromide is an ionic compound with the chemical form MgBr2 what does the 2 tell you
Answer:
The number of Bromine combining magnesium
Explanation:
The subscript gives the number of atom/s combining to form a compound. For this problem, 1 atom of Mg combines with 2 atoms of Br.
To form the ionic combine, Mg will lose two electrons. A bromine atom requires just one electron to have a complete octet. So, two bromine atoms will be needed to complete the bonding process.
Therefore, Mg loses two electrons to two Br atoms and the electrostatic attraction from the charges created forms the ionic bond.
The number 2 represents the number of bromine atoms.
An ionic compound is formed when the complete transfer of electrons takes place from one element (usually metals) to another element (usually non-metals).The element losing electron (metal) forms a positive ion known as a cation while the element gaining electron (non-metal) forms a negative ion known as an anion.Magnesium bromide is formed by the combination of magnesium (metal) and bromine (non-metal).
The valency of magnesium is 2 while that of bromine is 1. To form a neutral compound 2 moles of bromine ion combines with 1 mole of magesium ion.
Thus, the number 2 represents the number of bromine atoms.

Answer:
2 PO₄³⁻(aq) + 3 Mg²⁺(aq) ⇒ Mg₃(PO₄)₂(s)
Explanation:
Let's consider the molecular equation that occurs when aqueous solutions of lithium phosphate and magnesium nitrate are mixed.

Answer:
Products
Explanation:
Reactants → Products
Chemical reactions are characterized by the formation of new products, and the making and breaking off strong chemical bonds.
Answer: They are the PRODUCTS of the reaction.
Explanation: In a chemical reaction, there are the REACTANTS and the PRODUCTS.
The reactants are the "ingredients" in the chemical formula. They are what are being chemically combined in a way.
The products are the "meal," or what the reactants combined to create.
For example, when creating salt or NaCl, this is essentially the formula:
Na + Cl = NaClIn this formula, Na (sodium) and Cl (chlorine) are the reactants. NaCl (sodium chloride, aka salt) is the product.
