Answer:
Average speed or just speed
Explanation:
Average speed is the total distance an object travels divided by the total amount of time it took to travel the distance.
Cl is stable as a diatomic molecule where the 2 Cl atoms are held together by a covalent bond
molar mass of the diatomic molecule is 70.9 g/mol
therefore 70.9 g of Cl₂ is - 1 mol
then 140 g of Cl₂ is - 1/70.9 x 140 = 1.97 mol
there are 1.97 mol of Cl₂ present
Answer:
The Celsius scale is in general use wherever metric units have become accepted, and it is used in scientific work everywhere. Kelvin temperature scale is the base unit of thermodynamic temperature measurement in the International System (SI) of measurement
Answer:
The rate of the catalyzed reaction will increase by a 1.8 × 10⁵ factor.
Explanation:
The rate of a reaction (r) is proportional to the rate constant (k). We can find the rate constant using the Arrhenius equation.
where,
A: collision factor
Ea: activation energy
R: ideal gas constant
T: absolute temperature (125°C + 273 = 398 K)
For the uncatalized reaction,
For the catalized reaction,
The ratio kC to kU is 6.0 × 10⁻⁸A/3.4 × 10⁻¹³A = 1.8 × 10⁵
Answer:
The programs take two-dimensional images and allow the user to manipulate cubes and prisms to create their design sketches.
Explanation:
Instead of working with squares and triangles, the programs allow the users to manipulate cubes and prisms to create their design sketches. Additionally, the programs can take two-dimensional pictures and convert them to possible three-dimensional images.
I got you bro :)
Sorry he took your points :(
