Answer:

387 g/mol

Explanation:

The molar mass is a ratio comparing a substance's mass and molar value. The specific ratio looks like this:

Molar Mass (g/mol) = mass (g) / moles

You can plug the given values into the ratio to find the molar mass.

Molar Mass = mass / moles

Molar Mass = 0.406 g / 0.00105 mol

Molar Mass = 387 g/mol

There are four different starting molecules that one might use to synthesize the illustrated alkyl halide as the major product u
Mkey [24]

Answer:

Explanation:

An electrophilic addition reaction occurs when an electrophile attacks a substrate, with the end result being the inclusion of one or many comparatively straightforward molecules along with multiple bonds.

In the given question, the hydrogen bromide provides the electrophile while the bromide is the nucleophile. The mechanism proceeds with the attack of the electrophile on the carbon, followed by deprotonation. This process is continued with a formation of carbocation and the bromide(nucleophile) finally bonds to the carbocation to form a stable product.

The first diagram showcases the possible various starting molecules for the synthesis while the second diagram illustrates their mechanism.

How does the arrangement of particles determine the physical properties of different states of matter?​
Usimov [2.4K]

Answer:

See explanation

Explanation:

Matter may exist in three phases; solid, liquid and gas. The state in which matter exists depends on the extent of intermolecular forces operating in the substance.

In solid particles, the molecules that compose the solid are close together because the molecules of a solid do not move from place to place but they continue to vibrate about their fixed position.

For liquids, the molecules that compose a liquid are in random motion but are less energetic than molecules of a gas.

In gases, the molecules are not held together at all. The molecules of a gas have the highest degree of freedom. They move from one point another at a high velocity.

Hence, the order of increasing degree of movement of the particles in different states of matter = solids<liquids< gases.

Solids have well arranged particles, the molecules of a liquid are a little more disorderly than liquid particles while gas particles are the most disorderly of all the states of matter.

How many joules are needed to warm 675 grams of water (specific heat= 4.186 J/g degrees Celsius) from 12 degrees Celsius to 85 d
Naya [18.7K]
85-12 = 73 degrees needed
4.186 J/degree Celsius, so 
73 degrees * 4.186 J/degree = 305.578 J to raise 1 gram 73 degrees
there are 675 grams, so 305.578 * 675 = 206265.15 J

2.06 x 10^5 J are needed
