A student needs to convert a volume of 3 Tbsp (tablespoons) to mL. The student finds out that 1 tablespoon is equivalent to 14.7

garri49 [273]

Answer:

The conversion factor is 14.79 mL/Tbsp.

Explanation:

To do an unity conversiton, we can make a factor by a ratio transformation:

$3 Tbsp * \frac{14.79 mL}{1Tbsp}$

So, the conversion factor is 14.79 mL/Tbsp and 3 Tbsp has 44.37 mL.

When the potential difference across a lamp is 3.3V the current is 0.15 calculate the resistance of the lamp and give the unit

marissa [1.9K]

Answer:

22Ω

Explanation:

Given parameters:

Potential difference = 3.3V

Current = 0.15A

Unknown:

Resistance = ?

Solution:

According to ohm's law, potential difference, current and resistance are related by the expression below;

V = I R

where V is the voltage

I is the current

R is the resistance

3.3 = 0.15 x R

R = $\frac{3.3}{0.15}$ = 22Ω

Draw the major organic product(s) for the reaction. The starting material is a benzene ring with one substituent. The substituen

Mice21 [21]

Answer:

See Explanation

Explanation:

In electrophilic aromatic substitution, the benzene ring undergoes substitution when it is reacted with suitable electrophiles.

The products of electrophilic aromatic substitution depends on the substituents already present on the benzene ring. Some substituents activate the ring towards electrophilic substitution and direct the incoming electrophile to the ortho and para positions on the ring while some substituents deactivate the benzene ring towards electrophilic substitution and direct the incoming electrophlle to the meta position on the ring.

The amide substituent is moderately activating and is an ortho, para director hence the products shown in the mage attached to this answer.
