( If this is true then why is there a reaction?) The magnesium strip corrodes, leaving a dark messy liquid.

How many centimeters are in 4m 62 cm?
1 meter = 100 cm 4m 20cm = 4 x 100 + 20 cm = 420 cm
What is the acceleration of a 100 kg canoe that feels a force of 1000N?
4m /s
How long is 4m in feet?
By unit of length and distance and conversion ,we can say that 1 m=3.28 4 m =13.12 feet
What force is necessary to stop an 80kg bicyclist in 10s if she is riding at 4ms?
First, you must find the acceleration. You can do so using the following kinematics equation: V=V0+at (V is the final velocity, Vo is the initial velocity, a is acceleration and t is time.) The object ends up stopping, so V = 0. V0 is given as 4 m/s and t is given as 10s. So: 0 = 4m/s + a(10s) -4m/s = a(10s) (-4m/s)/(10s) = a -0.4m/s2 = a Now you can use Newton's Second Law equation to find the force. F=ma (F is force, m is mass, and a is acceleration.) Mass is given as 80kg, and the acceleration has been calculated to be -0.4m/s2. F=(80kg)(-0.4m/s2) F= -32 N
A railroad diesel engine coasting at 10 Kmh runs into a stationary flatcar The diesel weighs four times as much as the flatcar. How fast do the cars move when they stick together upon collision?
There are no forces external to the engine and car involved here*, thus this is a case of conservation of momentum. Note, an unknown amount of energy is absorbed by the couplers and other parts of the engine and car, so the conservation of energy equation is not useful here. Momentum = velocity X mass Since momentum is conserved, the total velocity X mass before the collision will equal total velocity X mass after the collision. If we define the mass of the car as M, then the mass of the engine is 4M Let: the initial velocity of the engine = Ve1 = 10Kmh the initial velocity of the car = Vc1 = 0 Kmh the final velocity = V2 (it is the same for both the car and the engine) So the initial momentum is: (Ve1) (4M) + (Vc1) (M) = (10) (4M) + (0) (M) = 40M The final momentum is: (V2) (4M + M) = (V2) (5M) = 5V2M Setting the initial momentum equal to the final momentum gives: 40M = 5V2M Doing the algebra gives: 40 = 5V2 8 = V2 So, the answer is the final velocity is 8 Kmh *We are assuming friction of the wheels on the track is negligible and that the track is level so that gravity can be ignored.
How do you solve 4m-4 equals 4m?
It has no solution since subtracting 4m from both sides leads to -4 = 0 which is not true.

Moles of H2SO4 in 20 ml of 4M solution?
The answer is 0,08 mol.
You need to prepare a 4M concentrated solution for a lab and only need 500 mL of total solution. If you use enough water to bring the volume to 500 mL how many grams of sodium chloride would you need?
You need 116,88 g dried and pure sodium chloride.
What is the solution for m given the equation 4m - 29 equals -105?
m = -19
When 80g of sodium hydroxide are dissolved in water to make 0.500 of a solution what is the molarity?

How many grams of NaCl would you use to make 100ml of a 4M solution?
The Molecular Weight of NaCl = 58.5 So to make 1L of 4M NaCl solution you need 4*58.5=234g of NaCl So to make 100mL of the above solution you need 23.4 grams of NaCl
How many grams of LiCl would you use to make 20 ml of a 4M solution?
3.3912
