2.	write the chemical equation for the chemical reaction takes place when thus formed compound is threated with the hydrochloric acid
Answer» The GAS thus formed is an effervescent carbon dioxide gas when calcium carbonate reacts with hydrochloric acid. The carbon dioxide gas also acts as an extinguisher for fires. Hence, the BURNING candle is extinguished. The metal compound A, therefore, constitutes calcium carbonate. Hence metal compound A is CaCO3 The Gas evolved is CO2 CaCO3 + 2HCl → CaCl2 + CO2 + H2O

The GAS thus formed is an effervescent carbon dioxide gas when calcium carbonate reacts with hydrochloric acid. The carbon dioxide gas also acts as an extinguisher for fires. Hence, the BURNING candle is extinguished. The metal compound A, therefore, constitutes calcium carbonate.

Hence metal compound A is CaCO3

The Gas evolved is CO2

3.	An object is placed in front of a convex mirror 40 cm and of focal length 20 cm ,find the nature ,size and position of image
Answer» Concept:- Here, It is given the object distance from the pole and the focal length of the mirror. We have to find the nature, size and position of the image. To find this we use some certain formula. Let's Find Given:- Distance of object from pole is of 40 cm. Focal length of the mirror is of 20 cm. To Find:- Size, Nature and Position of the image ? ASSUMPTION:- Let, Object-distance be u. Image-distance be v. Focal-length be f. Image-height be $\sf{h_e}$ . Object-height be $\sf{h_o}$ . Solution:- Now, we use certain formula to find the Position of the Image. $\sf{\Longrightarrow \dfrac{1}{v} + \dfrac{1}{u} = \dfrac{1}{f}}$ $\sf{Here,\ u = -40\ cm\ \ and\ \ f = 20\ cm}$ So, putting the values we get, $\sf{\Longrightarrow \dfrac{1}{v} + \dfrac{1}{-40} = \dfrac{1}{20}}$ $\sf{\Longrightarrow \dfrac{1}{v} = \dfrac{1}{20} - \bigg( \dfrac{1}{-40}\bigg)}$ Taking L.C.M of 20 and 40, $\sf{\Longrightarrow \dfrac{1}{v} = \dfrac{2 + 1}{40}}$ $\sf{\Longrightarrow \dfrac{1}{v} = \dfrac{3}{40}}$ By Cross multiplication we get, $\sf{\Longrightarrow 3v = 40}$ $\sf{\Longrightarrow v = \dfrac{40}{3}\ cm\ \ or\ \ 13\dfrac{1}{3}\ cm}$ $\sf{Hence,\ Position\ of\ image\ is\ \dfrac{40}{3}\ cm\ behind\ the\ mirror.}$ Note:- [The image will be behind the mirror because it is positive and from sign convention of convex mirror we get the positive image behind the mirror and convex mirror FORMS image behind the mirror.] Now, to find size of the image we will use certain formula $\sf{\Longrightarrow \dfrac{h_o}{h_e} = \dfrac{-v}{u}}$ $\sf{Here,\ u = 40\ cm\ \ and\ \ v = \dfrac{40}{3}\ cm}$ So, Putting all the values we get, $\sf{\Longrightarrow \dfrac{h_o}{h_e} = \dfrac{\dfrac{-40}{3}}{-40}}$ $\sf{\Longrightarrow \dfrac{h_o}{h_e} = \dfrac{1}{3}}$ By cross multiplication we get, $\sf{\Longrightarrow 3h_o = 1h_e}$ $\sf{\Longrightarrow h_e = 3h_o}$ $\sf{Hence, Image\ is\ 3\ times\ greater\ than\ size\ of\ object.}$ Nature $\longrightarrow$ VIRTUAL, Erect and DIMINISHED. The positive sign shows the image is virtual and erect.

3.

An object is placed in front of a convex mirror 40 cm and of focal length 20 cm ,find the nature ,size and position of image

Answer»

Concept:-

Here, It is given the object distance from the pole and the focal length of the mirror. We have to find the nature, size and position of the image. To find this we use some certain formula. Let's Find

Given:-

Distance of object from pole is of 40 cm.
Focal length of the mirror is of 20 cm.

To Find:-

Size, Nature and Position of the image ?

ASSUMPTION:-

Let, Object-distance be u.

Image-distance be v.

Focal-length be f.

Image-height be $\sf{h_e}$ .

Object-height be $\sf{h_o}$ .

Solution:-

Now, we use certain formula to find the Position of the Image.

$\sf{\Longrightarrow \dfrac{1}{v} + \dfrac{1}{u} = \dfrac{1}{f}}$

$\sf{Here,\ u = -40\ cm\ \ and\ \ f = 20\ cm}$

So, putting the values we get,

$\sf{\Longrightarrow \dfrac{1}{v} + \dfrac{1}{-40} = \dfrac{1}{20}}$

$\sf{\Longrightarrow \dfrac{1}{v} = \dfrac{1}{20} - \bigg( \dfrac{1}{-40}\bigg)}$

Taking L.C.M of 20 and 40,

$\sf{\Longrightarrow \dfrac{1}{v} = \dfrac{2 + 1}{40}}$

$\sf{\Longrightarrow \dfrac{1}{v} = \dfrac{3}{40}}$

By Cross multiplication we get,

$\sf{\Longrightarrow 3v = 40}$

$\sf{\Longrightarrow v = \dfrac{40}{3}\ cm\ \ or\ \ 13\dfrac{1}{3}\ cm}$

$\sf{Hence,\ Position\ of\ image\ is\ \dfrac{40}{3}\ cm\ behind\ the\ mirror.}$

Note:- [The image will be behind the mirror because it is positive and from sign convention of convex mirror we get the positive image behind the mirror and convex mirror FORMS image behind the mirror.]

Now, to find size of the image we will use certain formula

$\sf{\Longrightarrow \dfrac{h_o}{h_e} = \dfrac{-v}{u}}$

$\sf{Here,\ u = 40\ cm\ \ and\ \ v = \dfrac{40}{3}\ cm}$

So, Putting all the values we get,

$\sf{\Longrightarrow \dfrac{h_o}{h_e} = \dfrac{\dfrac{-40}{3}}{-40}}$

$\sf{\Longrightarrow \dfrac{h_o}{h_e} = \dfrac{1}{3}}$

By cross multiplication we get,

$\sf{\Longrightarrow 3h_o = 1h_e}$

$\sf{\Longrightarrow h_e = 3h_o}$

$\sf{Hence, Image\ is\ 3\ times\ greater\ than\ size\ of\ object.}$

Nature $\longrightarrow$ VIRTUAL, Erect and DIMINISHED.

The positive sign shows the image is virtual and erect.

8.	Which of the following compounds are used as agents to determine Glomerular Filtration Rate? (1 Marks) A) Calcium ion B) Albumin C) Creatinine D) Calcium carbonate
Answer» Explanation: The kidneys play a vital role in the excretion of waste products and toxins such as urea, CREATININE and uric acid, regulation of extracellular fluid volume, serum osmolality and electrolyte CONCENTRATIONS, as well as the production of hormones like erythropoietin and 1,25 dihydroxy vitamin D and renin. The functional unit of the kidney is the nephron, which consists of the glomerulus, proximal and distal tubules, and COLLECTING duct. Assessment of renal FUNCTION is important in the management of patients with kidney disease or pathologies affecting renal function. Tests of renal function have utility in identifying the presence of renal disease, monitoring the response of kidneys to treatment, and determining the progression of renal disease. According to the National Institutes of Health, the overall prevalence of chronic kidney disease (CKD) is approximately 14%. Worldwide, the most common causes of CKD are hypertension and diabetes.
