What does Nb stand for on the periodic table? Pls help! Need aware soon

Answers

Answer 1

Answer: it stands for niobium which was discovered in 1801 by Charles Hatchett of Brittan. It is ussed in welding rods, air fraim systems, superconductive magnets. It gets its name from iobe, the daughter of King Tantalus of the Greek myth. Niobium was considered identical to Tantalum, named after Tantalus, until 1884. Resists corrosin due to an oxide film. It is used in aviation industry

Answer 2

Answer: it stands for niobium

For the slow receptors, the likelihood of summation is ________ by the ________ of time required for those responses to decay.A) decreased : short period
B) increased : short period
C) decreased : long period
D) increased : long period
E) unaffected : long period

Answers

Answer:

Increased:long period

Explanation:

your welcome:)

Final answer:

Slow receptors, which respond to stimuli over longer durations, are more likely to have a cumulative or 'summation' effect. The likelihood of this summation increases with the length of time required for the responses to decay. This mechanism plays a critical role in cognitive functions such as learning and memory.

Explanation:

In the context of neuronal signaling, when we speak about slow receptors, we are referring to those that respond to stimuli at a slower pace, often due to a longer duration of transmitter binding, and therefore have a higher likelihood of summation compared to the fast receptors.

The concept of summation refers to the cumulative effect of a series of neural responses that take time to diminish. In this case, the likelihood of summation is increased by the long period of time required for those responses to decay. Thus, the correct answer to your question would be option D) increased : long period. This is because the longer the responses take to decay, the more likely they are to accumulate or summate.

It is also important to note that this process significantly contributes to the cognitive functions of the brain, such as memory and learning by facilitating the creation of long term potentiation within neural networks.

What is the percent composition by mass of hydrogen in NH4HCO3 (gram-formula mass = 79 grams/mole)?

Answers

Answer:The percent composition by mass of hydrogen in $NH_4HCO_3$ is 6.32 %.

Explanation:

Molecular mass of the $NH_4HCO_3$ = 79 g/mol

Mass of the hydrogen atom present in one formula unit of $NH_4HCO_3$ :

$= 5* \text{(atomic mass of hydrogen)}=5* 1 g/mol= 5 g/mol}$

$\text{percentage of hydrogen}=\frac{\text{mass of the hydrogen in}NH_4HCO_3}{\text{molar mass of}NH_4HCO_3}* 100$

$\text{percentage of hydrogen}=(5g/mol)/(79 g/mol)* 100=6.32\%$

The percent composition by mass of hydrogen in $NH_4HCO_3$ is 6.32 %.

Answers: 6.3%

What mass of anhydrous solute is needed to prepare 500 mL of 0.032 M NaF(aq)? Answer in units of g.

Answers

Volume 500 mL in liters : 500 / 1000 = 0.5 L

Molar Mass NaF = 41.98 g/mol

Molarity = 0.032 M

Mass = Molarity * molar mass * volume

Mass = 0.032 * 41.98 * 0.5

= 0.67168 g of NaF(aq)

Simple chem question - please help!Given the equation: N2 +2O2 → 2NO2, what mass of oxygen is required to react completely with 7g of nitrogen?

A) 8 g
B) 16 g
C) 32 g
D) 64 g

Answers

Molar mass O₂ = 32.0 g/mol and N₂ = 28.0 g/mol

N₂ +2 O₂ → 2 NO₂

28.0 g -------> 32.0 * 2
7 g ----------> ?

Mass of O₂ = 7 * 32.0 * 2 / 28.0

Mass of O₂ = 448 / 28.0

= 16 g of O₂

Answer B

How does adding salt affect the freezing point of water?

Answers

One of the colligative properties of water is the freezing point depression. A colligative property is a change in the property of water due to some amount of solute. Adding salt will lower down the freezing point of water which means that more heat would be needed to bring the boil to freeze.

When adding salt, the more you add the freezing point drops. The sodium and chlorine ions from the salt get in the way of the water molecules. This makes it harder for them to be rearranged into crystals. Salt prevents ice from staying solid because it raises the temperature .
