What type of grass is poisioness

ikadub [295]

Answer: Tall fescue can be harmful to grazing cattle and horses because the grass can become tough and infected with endophytes, causing poor grazing. Switchgrass and tall fescue are less likely to be poisonous to dogs, cats or humans than to horses or cattle, but eating either of them might cause stomach upset.

What are the various adverse effects of chemistry

Kisachek [45]

Answer:

Chemistry is the reaction between certain elements to create a new compound which may happen naturally but is mostly man made and hence has lot of good as well as adverse effects.

Explanation:

The product or compound that we get and the energy or outcome we receive is the ultimate result that decides whether chemical reaction that has happened is good or bad.

There are reactions that may cause pain and suffering to living beings and are also able to Infuse damage and destruction are are adverse nature. they can also change the course of nature hence are are dangerous.

An analytical chemist weighs out 0.188 g of an unknown triprotic acid into a 250 mL volumetric flask and dilutes to the mark wit

Anon25 [30]

Answer: The molar mass of unknown triprotic acid is 97.66 g/mol

Explanation:

To calculate the molarity of acid, we use the equation given by neutralization reaction:

$n_1M_1V_1=n_2M_2V_2$

where,

$n_1,M_1\text{ and }V_1$ are the n-factor, molarity and volume of triprotic acid

$n_2,M_2\text{ and }V_2$ are the n-factor, molarity and volume of base which is NaOH.

We are given:

$n_1=3\\M_1=?M\\V_1=250mL\\n_2=1\\M_2=0.0600M\\V_2=95.9mL$

Putting values in above equation, we get:

$3\times M_1\times 250=1\times 0.0600\times 95.9\\\\M_1=0.0077M$

To calculate the molecular mass of solute, we use the equation used to calculate the molarity of solution:

$\text{Molarity of the solution}=\frac{\text{Mass of solute}\times 1000}{\text{Molar mass of solute}\times \text{Volume of solution (in mL)}}$

We are given:

Molarity of solution = 0.0077 M

Given mass of triprotic acid = 0.188 g

Volume of solution = 250 mL

Putting values in above equation, we get:

$0.0077M=\frac{0.188\times 1000}{\text{Molar mass of triprotic acid}\times 250}\\\\\text{Molar mass of triprotic acid}=97.66g/mol$

Hence, the molar mass of unknown triprotic acid is 97.66 g/mol

How much heat is required to increase the temperature of 10.0 grams of water 6.0oC? (The specific heat of water is 4.18 J/g x oC

scoray [572]

Heat required in a system can be calculated by multiplying the given mass to the specific heat capacity of the substance and the temperature difference. It is expressed as follows:

Heat = mC (T2-T1)
Heat = 10.0 g (4.18 J/g-C ) ( 6.0 C )
Heat = 250.8 J
