please help me I cant remember the parts of the flower and I really need help.

Answer:

a greater profit......

Explanation:

E = hf

c= f × lamda

f= c/ lamda

c= speed of light

f= frequency

lamda = wavelength

E = h c/ lamda

E = 6.626 × 10^-34 Js × 3 × 10^8 ms-1 / 589 × 10^-9 m

= 3.37 × 10^15 J

Explanation:

Answer: Lipids are one of the important nutrients needed by the body to supply energy and essential fatty acids required by the organism. Solid alcohols are a class of steroids, which are steroids containing hydroxyl groups. Lipids is a general term for oils, fats and lipids. 2, the characteristics are different: fat consists of c, h, o three elements. Fats are triacylglycerides made up of glycerol and fatty acids.

Answer:

atomic # 38 or strontium (Sr)

Explanation:

Which ion with a

+2charge has the electron configuration

1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6?

ADD THE ELECTRONS AND ADD 2 MORE  FOR THE +2 CHARGE

so

2 +2 +6 +2 +6 +2 + 10 +  6 +2  

so if it is now neutral (you added 2 e's to ofsetr the +2 charge) it has 38

protons, so it is atomic # 38 or strontium (Sr)

Answer:

3. 0.819L (819 mL)

Explanation: Before we go about solving this, we need to do some conversions prior to using the gas law, the gas law is as follows...

P(atm)*V(L)=n(mol)*r(constant)*T(in kelvin)

So here are all the conversions you need.

620 mm Hg -> 0.816 atm

1140 mL -> 1.14 L

37 C -> 310.15 K

After plugging in our new converted values, we will proceed to solve the number of moles of the gas present, our n value, so our equation will look like this...(Note: Constant r in this case is 0.08206 L*atm/K*mol)

(0.816 atm)(1.14 L) = n(0.08206)(310.15)

Solving for n we get 0.03653 moles.

Now our second part is to figure out the volume AT STP (standard temperature/pressure). In the STP conditions, your temperature defaults to 0 C (273.15 K) and 1 atm. Now there is an easier way to do this, but I'll also show the more comprehensive way. Here is the easier method...

Since 1 mole of every gas occupies 22.4 L at STP, we can simply multiply this by our number of moles. So (22.4L)(0.3653 mol) to give us 0.818272.

However, a more accurate answer can be given like this...

Plugging n back into the same equation and this time resetting pressure to 1 atm and temperature to 273.15 K and conserving our number of moles we get...

(1 atm)(v) = (0.03653 mol)(0.08206)(273.15 K)

v = (0.03653)(0.08206)(273.15)

v = 0.8188 L = 0.819 L or 819 mL

Answer:

Explanation:

Givens

v1 = 375 cm^3

P1 = 770 mm Hg

V2 = ?

P2 = 750 mm Hg

Formula

V1 P1 = V2 P2

Solution

375 * 770 = V2 * 750    Combine the left

288750 = V2 * 750       Divide both sides by 750

288750/750 = V2

V2 = 385

Explanation:

If acid comes in contact with your skin, because having an excessive amount of base can also be harmful. Acid is weakened and rendered ineffective by water.

A chemical species known as an acid absorbs electrons and/or provides protons or hydrogen ions. When a hydrogen atom is bound to an acid, it can release (dissociate) and produce a cation as well as an anion in water. A substance's acidity and solution pH increase according to the amount of hydrogen ions it produces.

There are various definitions for acids. When someone uses the term "an acid," they typically mean an Arrhenius or Brnsted-Lowry acid. Often, a Lewis acid being referred to as a "Lewis acid." If acid comes in contact with your skin, because having an excessive amount of base can also be harmful. Acid is weakened and rendered ineffective by water.

Therefore, if acid comes in contact with your skin, because having an excessive amount of base can also be harmful. Acid is weakened and rendered ineffective by water.

Mercury is a compound denser than water and when this happen, it stays lower.

So, in this case, water stays higher than mercury because its density is low.

The level is different by a factor of 13.6 times taller.
